| /** |
| * The DOMConfiguration interface represents the configuration of |
| * a document and maintains a table of recognized parameters. |
| * Using the configuration, it is possible to change |
| * Document.normalizeDocument behavior, such as replacing |
| * CDATASection nodes with Text nodes or |
| * specifying the type of the schema that must be used when the |
| * validation of the Document is requested. DOMConfiguration |
| * objects are also used in [DOM Level 3 Load and Save] in |
| * the DOMLSParser and DOMLSSerializer interfaces. |
| * |
| * The DOMConfiguration distinguish two types of parameters: |
| * boolean (boolean parameters) and DOMUserData |
| * (parameters). The names used by the DOMConfiguration object are |
| * defined throughout the DOM Level 3 specifications. Names are |
| * case-insensitive. To avoid possible conflicts, as a |
| * convention, names referring to boolean parameters and |
| * parameters defined outside the DOM specification should be made |
| * unique. Names are recommended to follow the XML name |
| * production rule but it is not enforced by the DOM |
| * implementation. DOM Level 3 Core Implementations are required |
| * to recognize all boolean parameters and parameters defined in |
| * this specification. Each boolean parameter state or parameter |
| * value may then be supported or not by the implementation. Refer |
| * to their definition to know if a state or a value must be |
| * supported or not. |
| * |
| * Note: Parameters are similar to features and properties used in |
| * SAX2 [SAX]. |
| * |
| * The following list of parameters defined in the DOM: |
| * |
| * "error-handler" |
| * [required] |
| * A DOMErrorHandler object. If an error is |
| * encountered in the document, the implementation will call |
| * back the DOMErrorHandler registered using this |
| * parameter. |
| * When called, DOMError.relatedData will contain the |
| * closest node to where the error occured. If the |
| * implementation is unable to determine the node where the |
| * error occurs, DOMError.relatedData will contain the |
| * Document node. Mutations to the document from |
| * within an error handler will result in implementation |
| * dependent behaviour. |
| * |
| * "schema-type" |
| * [optional] |
| * A DOMString 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. |
| * |
| * Note: For XML Schema [XML Schema Part 1], |
| * applications must use the value |
| * "http://www.w3.org/2001/XMLSchema". For XML DTD |
| * [XML 1.0], applications must use the value |
| * "http://www.w3.org/TR/REC-xml". Other schema languages |
| * are outside the scope of the W3C and therefore should |
| * recommend an absolute URI in order to use this method. |
| * |
| * "schema-location" |
| * [optional] |
| * A DOMString object containing a list of URIs, |
| * separated by white spaces (characters matching the |
| * nonterminal production S defined in section 2.3 |
| * [XML 1.0]), that represents the schemas against |
| * which validation should occur. The types of schemas |
| * referenced in this list must match the type specified |
| * with schema-type, otherwise the behaviour of an |
| * implementation is undefined. If the schema type is XML |
| * Schema [XML Schema Part 1], only one of the XML |
| * Schemas in the list can be with no namespace. |
| * If validation occurs against a namespace aware schema, |
| * i.e. XML Schema, and the targetNamespace of a schema |
| * (specified using this property) matches the |
| * targetNamespace of a schema occurring in the instance |
| * document, i.e in schemaLocation attribute, the schema |
| * specified by the user using this property will be used |
| * (i.e., in XML Schema the schemaLocation attribute in the |
| * instance document or on the import element will be |
| * effectively ignored). |
| * |
| * Note: It is illegal to set the schema-location parameter |
| * if the schema-type parameter value is not set. It is |
| * strongly recommended that DOMInputSource.baseURI will be |
| * set, so that an implementation can successfully resolve |
| * any external entities referenced. |
| * |
| * The following list of boolean parameters (features) defined in |
| * the DOM: |
| * |
| * "canonical-form" |
| * |
| * true |
| * [optional] |
| * Canonicalize the document according to the rules |
| * specified in [Canonical XML]. 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. |
| * |
| * false |
| * [required] (default) |
| * Do not canonicalize the document. |
| * |
| * "cdata-sections" |
| * |
| * true |
| * [required] (default) |
| * Keep CDATASection nodes in the document. |
| * |
| * false |
| * [required] |
| * Transform CDATASection nodes in the document |
| * into Text nodes. The new Text node is |
| * then combined with any adjacent Text node. |
| * |
| * "comments" |
| * |
| * true |
| * [required] (default) |
| * Keep Comment nodes in the document. |
| * |
| * false |
| * [required] |
| * Discard Comment nodes in the Document. |
| * |
| * "datatype-normalization" |
| * |
| * true |
| * [required] |
| * Exposed normalized values in the tree. |
| * |
| * false |
| * [required] (default) |
| * Do not perform normalization on the tree. |
| * |
| * "discard-default-content" |
| * |
| * true |
| * [required] (default) |
| * Use whatever information available to the |
| * implementation (i.e. XML schema, DTD, the specified |
| * flag on Attr nodes, and so on) to decide what |
| * attributes and content should be discarded or not. |
| * Note that the specified flag on Attr nodes in |
| * itself is not always reliable, it is only reliable |
| * when it is set to false since the only case where |
| * it can be set to false is if the attribute was |
| * created by the implementation. The default content |
| * won't be removed if an implementation does not have |
| * any information available. |
| * |
| * false |
| * [required] |
| * Keep all attributes and all content. |
| * |
| * "entities" |
| * |
| * true |
| * [required] |
| * Keep EntityReference and Entity nodes |
| * in the document. |
| * |
| * false |
| * [required] (default) |
| * Remove all EntityReference and Entity |
| * nodes from the document, putting the entity |
| * expansions directly in their place. Text |
| * nodes are into "normal" form. Only |
| * EntityReference nodes to non-defined entities |
| * are kept in the document. |
| * |
| * "infoset" |
| * |
| * true |
| * [required] |
| * Only keep in the document the information defined |
| * in the XML Information Set [XML Information |
| * set]. |
| * This forces the following features to false: |
| * namespace-declarations, validate-if-schema, |
| * entities, datatype-normalization, cdata-sections. |
| * This forces the following features to true: |
| * whitespace-in-element-content, comments, |
| * namespaces. |
| * Other features are not changed unless explicitly |
| * specified in the description of the features. |
| * Note that querying this feature with getFeature |
| * returns true only if the individual features |
| * specified above are appropriately set. |
| * |
| * false |
| * Setting infoset to false has no effect. |
| * |
| * "namespaces" |
| * |
| * true |
| * [required] (default) |
| * Perform the namespace processing as defined in |
| * [XML Namespaces]. |
| * |
| * false |
| * [optional] |
| * Do not perform the namespace processing. |
| * |
| * "namespace-declarations" |
| * |
| * true |
| * [required] (default) |
| * Include namespace declaration attributes, specified |
| * or defaulted from the schema or the DTD, in the |
| * document. See also the section Declaring |
| * Namespaces in [XML Namespaces]. |
| * |
| * false |
| * [required] |
| * Discard all namespace declaration attributes. The |
| * Namespace prefixes are retained even if this |
| * feature is set to false. |
| * |
| * "normalize-characters" |
| * |
| * true |
| * [optional] |
| * Perform the W3C Text Normalization of the |
| * characters [CharModel] in the document. |
| * |
| * false |
| * [required] (default) |
| * Do not perform character normalization. |
| * |
| * "split-cdata-sections" |
| * |
| * true |
| * [required] (default) |
| * Split CDATA sections containing the CDATA section |
| * termination marker ']]>'. When a CDATA section is |
| * split a warning is issued. |
| * |
| * false |
| * [required] |
| * Signal an error if a CDATASection contains an |
| * unrepresentable character. |
| * |
| * "validate" |
| * |
| * true |
| * [optional] |
| * 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 [XML 1.0]. If validation errors |
| * are found, or no schema was found, the error |
| * handler is notified. Note also that normalized |
| * values will not be exposed to the schema in used |
| * unless the feature datatype-normalization is true. |
| * |
| * Note: validate-if-schema and validate are mutually |
| * exclusive, setting one of them to true will set the |
| * other one to false. |
| * |
| * false |
| * [required] (default) |
| * Only XML 1.0 non-validating processing must be |
| * done. Note that validation might still happen if |
| * validate-if-schema is true. |
| * |
| * "validate-if-schema" |
| * |
| * true |
| * [optional] |
| * Enable validation only if a declaration for the |
| * document element can be found (independently of |
| * where it is found, i.e. XML schema, DTD, or any |
| * other type or representation of schema). If |
| * validation errors are found, the error handler is |
| * notified. Note also that normalized values will not |
| * be exposed to the schema in used unless the feature |
| * datatype-normalization is true. |
| * |
| * Note: validate-if-schema and validate are mutually |
| * exclusive, setting one of them to true will set the |
| * other one to false. |
| * |
| * false |
| * [required] (default) |
| * No validation should be performed if the document |
| * has a schema. Note that validation must still |
| * happen if validate is true. |
| * |
| * "element-content-whitespace" |
| * |
| * true |
| * [required] (default) |
| * Keep all white spaces in the document. |
| * |
| * false |
| * [optional] |
| * Discard white space in element content while |
| * normalizing. The implementation is expected to use |
| * the isWhitespaceInElementContent flag on Text |
| * nodes to determine if a text node should be written |
| * out or not. |
| * |
| * The resolutions of entities is done using Document.baseURI. |
| * However, when the features "LS-Load" or "LS-Save" defined in |
| * [DOM Level 3 Load and Save] are supported by the DOM |
| * implementation, the parameter "entity-resolver" can also be |
| * used on DOMConfiguration objects attached to Document |
| * nodes. If this parameter is set, |
| * Document.normalizeDocument will invoke the entity |
| * resolver instead of using Document.baseURI. |
