<HR>
<DL>
<DT>public interface <B>DOMConfiguration</B></DL>
<P>
The <code>DOMConfiguration</code> interface represents the configuration
of a document and maintains a table of recognized parameters. Using the
configuration, it is possible to change
<code>Document.normalizeDocument()</code> behavior, such as replacing the
<code>CDATASection</code> nodes with <code>Text</code> nodes or
specifying the type of the schema that must be used when the validation
of the <code>Document</code> is requested. <code>DOMConfiguration</code>
objects are also used in [<a href='http://www.w3.org/TR/2004/REC-DOM-Level-3-LS-20040407'>DOM Level 3 Load and Save</a>]
in the <code>DOMParser</code> and <code>DOMSerializer</code> interfaces.
<p> The parameter names used by the <code>DOMConfiguration</code> object
are defined throughout the DOM Level 3 specifications. Names are
case-insensitive. To avoid possible conflicts, as a convention, names
referring to parameters defined outside the DOM specification should be
made unique. Because parameters are exposed as properties in the , names
are recommended to follow the section 5.16 Identifiers of [Unicode] with the addition of the character '-' (HYPHEN-MINUS) but it is not
enforced by the DOM implementation. DOM Level 3 Core Implementations are
required to recognize all parameters defined in this specification. Some
parameter values may also be required to be supported by the
implementation. Refer to the definition of the parameter to know if a
value must be supported or not.
<p ><b>Note:</b> Parameters are similar to features and properties used in
SAX2 [<a href='http://www.saxproject.org/'>SAX</a>].
<p> The following list of parameters defined in the DOM:
<dl>
<dt>
<code>"canonical-form"</code></dt>
<dd>
<dl>
<dt><code>true</code></dt>
<dd>[<em>optional</em>] Canonicalize the document according to the rules specified in [<a href='http://www.w3.org/TR/2001/REC-xml-c14n-20010315'>Canonical XML</a>],
such as removing the <code>DocumentType</code> node (if any) from the
tree, or removing superfluous namespace declarations from each element.
Note that this is limited to what can be represented in the DOM; in
particular, there is no way to specify the order of the attributes in the
DOM. In addition, Setting this parameter to <code>true</code> will also
set the state of the parameters listed below. Later changes to the state
of one of those parameters will revert "canonical-form" back to
<code>false</code>. Parameters set to <code>false</code>: "entities", "
normalize-characters", "cdata-sections". Parameters set to
<code>true</code>: "namespaces", "namespace-declarations", "well-formed",
"element-content-whitespace". Other parameters are not changed unless
explicitly specified in the description of the parameters.</dd>
<dt>
<code>false</code></dt>
<dd>[<em>required</em>] (<em>default</em>)Do not canonicalize the document.</dd>
</dl></dd>
<dt><code>"cdata-sections"</code></dt>
<dd>
<dl>
<dt>
<code>true</code></dt>
<dd>[<em>required</em>] (<em>default</em>)Keep <code>CDATASection</code> nodes in the document.</dd>
<dt><code>false</code></dt>
<dd>[<em>required</em>]Transform <code>CDATASection</code> nodes in the document into
<code>Text</code> nodes. The new <code>Text</code> node is then combined
with any adjacent <code>Text</code> node.</dd>
</dl></dd>
<dt>
<code>"check-character-normalization"</code></dt>
<dd>
<dl>
<dt><code>true</code></dt>
<dd>[<em>optional</em>] Check if the characters in the document are <a href='http://www.w3.org/TR/2004/REC-xml11-20040204/#dt-fullnorm'>fully
normalized</a>, as defined in appendix B of [<a href='http://www.w3.org/TR/2004/REC-xml11-20040204/'>XML 1.1</a>]. When a
sequence of characters is encountered that fails normalization checking,
an error with the <code>DOMError.type</code> equals to
"check-character-normalization-failure" is issued. </dd>
<dt><code>false</code></dt>
<dd>[<em>required</em>] (<em>default</em>)Do not check if characters are normalized.</dd>
</dl></dd>
<dt><code>"comments"</code></dt>
<dd>
<dl>
<dt>
<code>true</code></dt>
<dd>[<em>required</em>] (<em>default</em>)Keep <code>Comment</code> nodes in the document.</dd>
<dt><code>false</code></dt>
<dd>[<em>required</em>]Discard <code>Comment</code> nodes in the document.</dd>
</dl></dd>
<dt>
<code>"datatype-normalization"</code></dt>
<dd>
<dl>
<dt><code>true</code></dt>
<dd>[<em>optional</em>] Expose schema normalized values in the tree, such as <a href='http://www.w3.org/TR/2001/REC-xmlschema-1-20010502/#key-nv'>XML
Schema normalized values</a> in the case of XML Schema. Since this parameter requires to have schema
information, the "validate" parameter will also be set to
<code>true</code>. Having this parameter activated when "validate" is
<code>false</code> has no effect and no schema-normalization will happen.
<p ><b>Note:</b> Since the document contains the result of the XML 1.0
processing, this parameter does not apply to attribute value
normalization as defined in section 3.3.3 of [<a href='http://www.w3.org/TR/2004/REC-xml-20040204'>XML 1.0</a>] and is only
meant for schema languages other than Document Type Definition (DTD). </dd>
<dt>
<code>false</code></dt>
<dd>[<em>required</em>] (<em>default</em>) Do not perform schema normalization on the tree. </dd>
</dl></dd>
<dt>
<code>"element-content-whitespace"</code></dt>
<dd>
<dl>
<dt><code>true</code></dt>
<dd>[<em>required</em>] (<em>default</em>)Keep all whitespaces in the document.</dd>
<dt><code>false</code></dt>
<dd>[<em>optional</em>] Discard all <code>Text</code> nodes that contain whitespaces in element
content, as described in <a href='http://www.w3.org/TR/2004/REC-xml-infoset-20040204#infoitem.character'>
[element content whitespace]</a>. The implementation is expected to use the attribute
<code>Text.isElementContentWhitespace</code> to determine if a
<code>Text</code> node should be discarded or not.</dd>
</dl></dd>
<dt><code>"entities"</code></dt>
<dd>
<dl>
<dt>
<code>true</code></dt>
<dd>[<em>required</em>] (<em>default</em>)Keep <code>EntityReference</code> nodes in the document.</dd>
<dt>
<code>false</code></dt>
<dd>[<em>required</em>] Remove all <code>EntityReference</code> nodes from the document,
putting the entity expansions directly in their place. <code>Text</code>
nodes are normalized, as defined in <code>Node.normalize</code>. Only <a href='http://www.w3.org/TR/2004/REC-xml-infoset-20040204/#infoitem.rse'>
unexpanded entity references</a> are kept in the document. </dd>
</dl>
<p ><b>Note:</b> This parameter does not affect <code>Entity</code> nodes. </dd>
<dt>
<code>"error-handler"</code></dt>
<dd>[<em>required</em>] Contains a <code>DOMErrorHandler</code> object. If an error is
encountered in the document, the implementation will call back the
<code>DOMErrorHandler</code> registered using this parameter. The
implementation may provide a default <code>DOMErrorHandler</code> object.
When called, <code>DOMError.relatedData</code> will contain the closest
node to where the error occurred. If the implementation is unable to
determine the node where the error occurs,
<code>DOMError.relatedData</code> will contain the <code>Document</code>
node. Mutations to the document from within an error handler will result
in implementation dependent behavior. </dd>
<dt><code>"infoset"</code></dt>
<dd>
<dl>
<dt>
<code>true</code></dt>
<dd>[<em>required</em>]Keep in the document the information defined in the XML Information Set [<a href='http://www.w3.org/TR/2004/REC-xml-infoset-20040204/'>XML Information Set</a>]
.This forces the following parameters to <code>false</code>: "
validate-if-schema", "entities", "datatype-normalization", "cdata-sections
".This forces the following parameters to <code>true</code>: "
namespace-declarations", "well-formed", "element-content-whitespace", "
comments", "namespaces".Other parameters are not changed unless
explicitly specified in the description of the parameters. Note that
querying this parameter with <code>getParameter</code> returns
<code>true</code> only if the individual parameters specified above are
appropriately set.</dd>
<dt><code>false</code></dt>
<dd>Setting <code>infoset</code> to
<code>false</code> has no effect.</dd>
</dl></dd>
<dt><code>"namespaces"</code></dt>
<dd>
<dl>
<dt>

<dd>[<em>required</em>] (<em>default</em>) Perform the namespace processing as defined in . </dd>
<dt><code>false</code></dt>
<dd>[<em>optional</em>] Do not perform the namespace processing. </dd>
</dl></dd>
<dt>
<code>"namespace-declarations"</code></dt>
<dd> This parameter has no effect if the
parameter "namespaces" is set to <code>false</code>.
<dl>
<dt><code>true</code></dt>
<dd>[<em>required</em>] (<em>default</em>) Include namespace declaration attributes, specified or defaulted from
the schema, in the document. See also the sections "Declaring Namespaces"
in [<a href='http://www.w3.org/TR/1999/REC-xml-names-19990114/'>XML Namespaces</a>]

.</dd>
<dt><code>false</code></dt>
<dd>[<em>required</em>]Discard all namespace declaration attributes. The namespace prefixes (

<dd>[<em>optional</em>] <a href='http://www.w3.org/TR/2004/REC-xml11-20040204/#dt-fullnorm'>Fully
normalized</a> the characters in the document as defined in appendix B of [<a href='http://www.w3.org/TR/2004/REC-xml11-20040204/'>XML 1.1</a>]. </dd>
<dt>
<code>false</code></dt>
<dd>[<em>required</em>] (<em>default</em>)Do not perform character normalization.</dd>
</dl></dd>
<dt><code>"schema-location"</code></dt>
<dd>[<em>optional</em>] Represent a <code>DOMString</code> object containing a list of URIs,
separated by whitespaces (characters matching the <a href='http://www.w3.org/TR/2004/REC-xml-20040204#NT-S'>nonterminal
production S</a> defined in section 2.3 [<a href='http://www.w3.org/TR/2004/REC-xml-20040204'>XML 1.0</a>]), that
represents the schemas against which validation should occur, i.e. the
current schema. The types of schemas referenced in this list must match
the type specified with <code>schema-type</code>, otherwise the behavior
of an implementation is undefined. The schemas specified using this
property take precedence to the schema information specified in the
document itself. For namespace aware schema, if a schema specified using
this property and a schema specified in the document instance (i.e. using
the <code>schemaLocation</code> attribute) in a schema document (i.e.
using schema <code>import</code> mechanisms) share the same
<code>targetNamespace</code>, the schema specified by the user using this
property will be used. If two schemas specified using this property share
the same <code>targetNamespace</code> or have no namespace, the behavior
is implementation dependent. If no location has been provided, this
parameter is <code>null</code>.
<p ><b>Note:</b> The <code>"schema-location"</code> parameter is ignored
unless the "schema-type" parameter value is set. It is strongly
recommended that <code>Document.documentURI</code> will be set so that an
implementation can successfully resolve any external entities referenced. </dd>
<dt>
<code>"schema-type"</code></dt>
<dd>[<em>optional</em>] Represent a <code>DOMString</code> object containing an absolute URI
and representing the type of the schema language used to validate a
document against. Note that no lexical checking is done on the absolute
URI. If this parameter is not set, a default value may be provided by
the implementation, based on the schema languages supported and on the
schema language used at load time. If no value is provided, this
parameter is <code>null</code>.
<p ><b>Note:</b> For XML Schema [<a href='http://www.w3.org/TR/2001/REC-xmlschema-1-20010502/'>XML Schema Part 1</a>]
, applications must use the value
<code>"http://www.w3.org/2001/XMLSchema"</code>. For XML DTD [<a href='http://www.w3.org/TR/2004/REC-xml-20040204'>XML 1.0</a>],
applications must use the value
<code>"http://www.w3.org/TR/REC-xml"</code>. Other schema languages are
outside the scope of the W3C and therefore should recommend an absolute
URI in order to use this method. </dd>
<dt><code>"split-cdata-sections"</code></dt>
<dd>
<dl>
<dt>
<code>true</code></dt>
<dd>[<em>required</em>] (<em>default</em>)Split CDATA sections containing the CDATA section termination marker
']]&gt;'. When a CDATA section is split a warning is issued with a
<code>DOMError.type</code> equals to
<code>"cdata-sections-splitted"</code> and
<code>DOMError.relatedData</code> equals to the first
<code>CDATASection</code> node in document order resulting from the split.</dd>
<dt>
<code>false</code></dt>
<dd>[<em>required</em>]Signal an error if a <code>CDATASection</code> contains an
unrepresentable character.</dd>
</dl></dd>
<dt><code>"validate"</code></dt>
<dd>
<dl>
<dt><code>true</code></dt>
<dd>[<em>optional</em>] Require the validation against a schema (i.e. XML schema, DTD, any
other type or representation of schema) of the document as it is being
normalized as defined by [<a href='http://www.w3.org/TR/2004/REC-xml-20040204'>XML 1.0</a>]. If
validation errors are found, or no schema was found, the error handler is
notified. Schema-normalized values will not be exposed according to the
schema in used unless the parameter "datatype-normalization" is
<code>true</code>. This parameter will reevaluate:
<ul>
<li> Attribute nodes with
<code>Attr.specified</code> equals to <code>false</code>, as specified in
the description of the <code>Attr</code> interface;
</li>
<li> The value of the
attribute <code>Text.isElementContentWhitespace</code> for all
<code>Text</code> nodes;
</li>
<li> The value of the attribute
<code>Attr.isId</code> for all <code>Attr</code> nodes;
</li>
<li> The attributes
<code>Element.schemaTypeInfo</code> and <code>Attr.schemaTypeInfo</code>.
</li>
</ul>
<p ><b>Note:</b> "validate-if-schema" and "validate" are mutually
exclusive, setting one of them to <code>true</code> will set the other
one to <code>false</code>. Applications should also consider setting the
parameter "well-formed" to <code>true</code>, which is the default for
that option, when validating the document. </dd>
<dt><code>false</code></dt>
<dd>[<em>required</em>] (<em>default</em>) Do not accomplish schema processing, including the internal subset
processing. Default attribute values information are kept. Note that
validation might still happen if "validate-if-schema" is <code>true</code>

<dd>[<em>optional</em>]Enable validation only if a declaration for the document element can be
found in a schema (independently of where it is found, i.e. XML schema,
DTD, or any other type or representation of schema). If validation is
enabled, this parameter has the same behavior as the parameter "validate"
set to <code>true</code>.

<p> The resolution of the system identifiers associated with entities is
done using <code>Document.documentURI</code>. However, when the feature
"LS" defined in [<a href='http://www.w3.org/TR/2004/REC-DOM-Level-3-LS-20040407'>DOM Level 3 Load and Save</a>]
is supported by the DOM implementation, the parameter
"resource-resolver" can also be used on <code>DOMConfiguration</code>
objects attached to <code>Document</code> nodes. If this parameter is
set, <code>Document.normalizeDocument()</code> will invoke the resource
resolver instead of using <code>Document.documentURI</code>.
