 Without a default, the placeholder is left in the value if no value can be found. With a default, the default is used instead.
 
+The default value may contain all alphanumeric and punctuation characters and space except for a `;`. It may even be left out which leads to replacing the placeholder with the empty string.
+
 ## Type Support
 
 A placeholder can contain additional information like the type the value should be converted to.

 # Apache Felix Configuration Admin Service
 
-The OSGi Componendium Configuration Admin Service specifies a service, which allows for easy management of configuration data for configurable components. Basically a configuration is a list of name-value pairs. A cnfiguration is managed by management applications by asking the Configuration Admin Service for such configuration. After updating the configuration, it is sent back to the Configuration Admin Service. The Configuration Admin Service is like a central hub, which cares for persisting this configuration and also for distributing the configuration to interested parties. One class of such parties are the components to be configured. These are registered as `ManagedService` services. There is also a notion of `ManagedServiceFactory`, which allows for multiple configurations of the same kind to be applied.

 Staging a release candidate
 ===========================
 
 Staging a release starts by checking out a tagged version of the sources (replace r<n> by the actual release number, like "r1"):
 
-svn co https://svn.apache.org/repos/asf/felix/releases/org.apache.felix.dependencymanager-r<n>
+git clone -–depth 1 -b org.apache.felix.dependencymanager-r<n> http://gitbox.apache.org/repos/asf/felix-dev.git felix-dev-org.apache.felix.dependencymanager-r<n>
 
 The next step is to build/test the software and create the release/staging/ directory (where the source/jars will be packaged):

+/**
+ * RFC 1960-based Filter. Filter objects can be created by calling the
+ * constructor with the desired filter string. A Filter object can be called
+ * numerous times to determine if the match argument matches the filter string
+ * that was used to create the Filter object.
+ * <p>
+ * The syntax of a filter string is the string representation of LDAP search
+ * filters as defined in RFC 1960: <i>A String Representation of LDAP Search
+ * Filters</i> (available at http://www.ietf.org/rfc/rfc1960.txt). It should be
+ * noted that RFC 2254: <i>A String Representation of LDAP Search Filters</i>
+ * (available at http://www.ietf.org/rfc/rfc2254.txt) supersedes RFC 1960 but
+ * only adds extensible matching and is not applicable for this API.
+ * <p>
+ * The string representation of an LDAP search filter is defined by the
+ * following grammar. It uses a prefix format.
+ * 
+ * <pre>
+ *   &lt;filter&gt; ::= '(' &lt;filtercomp&gt; ')'
+ *   &lt;filtercomp&gt; ::= &lt;and&gt; | &lt;or&gt; | &lt;not&gt; | &lt;item&gt;
+ *   &lt;and&gt; ::= '&amp;' &lt;filterlist&gt;
+ *   &lt;or&gt; ::= '|' &lt;filterlist&gt;
+ *   &lt;not&gt; ::= '!' &lt;filter&gt;
+ *   &lt;filterlist&gt; ::= &lt;filter&gt; | &lt;filter&gt; &lt;filterlist&gt;
+ *   &lt;item&gt; ::= &lt;simple&gt; | &lt;present&gt; | &lt;substring&gt;
+ *   &lt;simple&gt; ::= &lt;attr&gt; &lt;filtertype&gt; &lt;value&gt;
+ *   &lt;filtertype&gt; ::= &lt;equal&gt; | &lt;approx&gt; | &lt;greater&gt; | &lt;less&gt;
+ *   &lt;equal&gt; ::= '='
+ *   &lt;approx&gt; ::= '&tilde;='
+ *   &lt;greater&gt; ::= '&gt;='
+ *   &lt;less&gt; ::= '&lt;='
+ *   &lt;present&gt; ::= &lt;attr&gt; '=*'
+ *   &lt;substring&gt; ::= &lt;attr&gt; '=' &lt;initial&gt; &lt;any&gt; &lt;final&gt;
+ *   &lt;initial&gt; ::= NULL | &lt;value&gt;
+ *   &lt;any&gt; ::= '*' &lt;starval&gt;
+ *   &lt;starval&gt; ::= NULL | &lt;value&gt; '*' &lt;starval&gt;
+ *   &lt;final&gt; ::= NULL | &lt;value&gt;
+ * </pre>
+ * 
+ * {@code &lt;attr&gt;} is a string representing an attribute, or key, in the
+ * properties objects of the registered services. Attribute names are not case
+ * sensitive; that is cn and CN both refer to the same attribute.
+ * {@code &lt;value&gt;} is a string representing the value, or part of one, of
+ * a key in the properties objects of the registered services. If a
+ * {@code &lt;value&gt;} must contain one of the characters ' {@code *}' or
+ * '{@code (}' or '{@code )}', these characters should be escaped by preceding
+ * them with the backslash '{@code \}' character. Note that although both the
+ * {@code &lt;substring&gt;} and {@code &lt;present&gt;} productions can produce
+ * the {@code 'attr=*'} construct, this construct is used only to denote a
+ * presence filter.
+ * <p>
+ * Examples of LDAP filters are:
+ * 
+ * <pre>
+ *   &quot;(cn=Babs Jensen)&quot;
+ *   &quot;(!(cn=Tim Howes))&quot;
+ *   &quot;(&amp;(&quot; + Constants.OBJECTCLASS + &quot;=Person)(|(sn=Jensen)(cn=Babs J*)))&quot;
+ *   &quot;(o=univ*of*mich*)&quot;
+ * </pre>
+ * <p>
+ * The approximate match ({@code ~=}) is implementation specific but should at
+ * least ignore case and white space differences. Optional are codes like
+ * soundex or other smart "closeness" comparisons.
+ * <p>
+ * Comparison of values is not straightforward. Strings are compared differently
+ * than numbers and it is possible for a key to have multiple values. Note that
+ * that keys in the match argument must always be strings. The comparison is
+ * defined by the object type of the key's value. The following rules apply for
+ * comparison: <blockquote>
+ * <TABLE BORDER=0>
+ * <TR>
+ * <TD><b>Property Value Type </b></TD>
+ * <TD><b>Comparison Type</b></TD>
+ * </TR>
+ * <TR>
+ * <TD>String</TD>
+ * <TD>String comparison</TD>
+ * </TR>
+ * <TR valign=top>
+ * <TD>Integer, Long, Float, Double, Byte, Short, BigInteger, BigDecimal</TD>
+ * <TD>numerical comparison</TD>
+ * </TR>
+ * <TR>
+ * <TD>Character</TD>
+ * <TD>character comparison</TD>
+ * </TR>
+ * <TR>
+ * <TD>Boolean</TD>
+ * <TD>equality comparisons only</TD>
+ * </TR>
+ * <TR>
+ * <TD>[] (array)</TD>
+ * <TD>recursively applied to values</TD>
+ * </TR>
+ * <TR>
+ * <TD>Collection</TD>
+ * <TD>recursively applied to values</TD>
+ * </TR>
+ * </TABLE>
+ * Note: arrays of primitives are also supported. </blockquote> A filter matches
+ * a key that has multiple values if it matches at least one of those values.
+ * For example,
+ * 
+ * <pre>
+ * Dictionary d = new Hashtable();
+ * d.put(&quot;cn&quot;, new String[] {
+ * 		&quot;a&quot;, &quot;b&quot;, &quot;c&quot;
+ * });
+ * </pre>
+ * 
+ * d will match {@code (cn=a)} and also {@code (cn=b)}
+ * <p>
+ * A filter component that references a key having an unrecognizable data type
+ * will evaluate to {@code false} .

-	 * RFC 1960-based Filter. Filter objects can be created by calling the
-	 * constructor with the desired filter string. A Filter object can be called
-	 * numerous times to determine if the match argument matches the filter
-	 * string that was used to create the Filter object.
-	 * 
-	 * <p>
-	 * The syntax of a filter string is the string representation of LDAP search
-	 * filters as defined in RFC 1960: <i>A String Representation of LDAP Search
-	 * Filters</i> (available at http://www.ietf.org/rfc/rfc1960.txt). It should
-	 * be noted that RFC 2254: <i>A String Representation of LDAP Search
-	 * Filters</i> (available at http://www.ietf.org/rfc/rfc2254.txt) supersedes
-	 * RFC 1960 but only adds extensible matching and is not applicable for this
-	 * API.
-	 * 
-	 * <p>
-	 * The string representation of an LDAP search filter is defined by the
-	 * following grammar. It uses a prefix format.
-	 * 
-	 * <pre>
-	 *   &lt;filter&gt; ::= '(' &lt;filtercomp&gt; ')'
-	 *   &lt;filtercomp&gt; ::= &lt;and&gt; | &lt;or&gt; | &lt;not&gt; | &lt;item&gt;
-	 *   &lt;and&gt; ::= '&amp;' &lt;filterlist&gt;
-	 *   &lt;or&gt; ::= '|' &lt;filterlist&gt;
-	 *   &lt;not&gt; ::= '!' &lt;filter&gt;
-	 *   &lt;filterlist&gt; ::= &lt;filter&gt; | &lt;filter&gt; &lt;filterlist&gt;
-	 *   &lt;item&gt; ::= &lt;simple&gt; | &lt;present&gt; | &lt;substring&gt;
-	 *   &lt;simple&gt; ::= &lt;attr&gt; &lt;filtertype&gt; &lt;value&gt;
-	 *   &lt;filtertype&gt; ::= &lt;equal&gt; | &lt;approx&gt; | &lt;greater&gt; | &lt;less&gt;
-	 *   &lt;equal&gt; ::= '='
-	 *   &lt;approx&gt; ::= '&tilde;='
-	 *   &lt;greater&gt; ::= '&gt;='
-	 *   &lt;less&gt; ::= '&lt;='
-	 *   &lt;present&gt; ::= &lt;attr&gt; '=*'
-	 *   &lt;substring&gt; ::= &lt;attr&gt; '=' &lt;initial&gt; &lt;any&gt; &lt;final&gt;
-	 *   &lt;initial&gt; ::= NULL | &lt;value&gt;
-	 *   &lt;any&gt; ::= '*' &lt;starval&gt;
-	 *   &lt;starval&gt; ::= NULL | &lt;value&gt; '*' &lt;starval&gt;
-	 *   &lt;final&gt; ::= NULL | &lt;value&gt;
-	 * </pre>
-	 * 
-	 * {@code &lt;attr&gt;} is a string representing an attribute, or key, in
-	 * the properties objects of the registered services. Attribute names are
-	 * not case sensitive; that is cn and CN both refer to the same attribute.
-	 * {@code &lt;value&gt;} is a string representing the value, or part of one,
-	 * of a key in the properties objects of the registered services. If a
-	 * {@code &lt;value&gt;} must contain one of the characters ' {@code *}' or
-	 * '{@code (}' or '{@code )}', these characters should be escaped by
-	 * preceding them with the backslash '{@code \}' character. Note that
-	 * although both the {@code &lt;substring&gt;} and {@code &lt;present&gt;}
-	 * productions can produce the {@code 'attr=*'} construct, this construct is
-	 * used only to denote a presence filter.
-	 * 
-	 * <p>
-	 * Examples of LDAP filters are:
-	 * 
-	 * <pre>
-	 *   &quot;(cn=Babs Jensen)&quot;
-	 *   &quot;(!(cn=Tim Howes))&quot;
-	 *   &quot;(&amp;(&quot; + Constants.OBJECTCLASS + &quot;=Person)(|(sn=Jensen)(cn=Babs J*)))&quot;
-	 *   &quot;(o=univ*of*mich*)&quot;
-	 * </pre>
-	 * 
-	 * <p>
-	 * The approximate match ({@code ~=}) is implementation specific but should
-	 * at least ignore case and white space differences. Optional are codes like
-	 * soundex or other smart "closeness" comparisons.
-	 * 
-	 * <p>
-	 * Comparison of values is not straightforward. Strings are compared
-	 * differently than numbers and it is possible for a key to have multiple
-	 * values. Note that that keys in the match argument must always be strings.
-	 * The comparison is defined by the object type of the key's value. The
-	 * following rules apply for comparison:
-	 * 
-	 * <blockquote>
-	 * <TABLE BORDER=0>
-	 * <TR>
-	 * <TD><b>Property Value Type </b></TD>
-	 * <TD><b>Comparison Type</b></TD>
-	 * </TR>
-	 * <TR>
-	 * <TD>String</TD>
-	 * <TD>String comparison</TD>
-	 * </TR>
-	 * <TR valign=top>
-	 * <TD>Integer, Long, Float, Double, Byte, Short, BigInteger, BigDecimal</TD>
-	 * <TD>numerical comparison</TD>
-	 * </TR>
-	 * <TR>
-	 * <TD>Character</TD>
-	 * <TD>character comparison</TD>
-	 * </TR>
-	 * <TR>
-	 * <TD>Boolean</TD>
-	 * <TD>equality comparisons only</TD>
-	 * </TR>
-	 * <TR>
-	 * <TD>[] (array)</TD>
-	 * <TD>recursively applied to values</TD>
-	 * </TR>
-	 * <TR>
-	 * <TD>Collection</TD>
-	 * <TD>recursively applied to values</TD>
-	 * </TR>
-	 * </TABLE>
-	 * Note: arrays of primitives are also supported. </blockquote>
-	 * 
-	 * A filter matches a key that has multiple values if it matches at least
-	 * one of those values. For example,
-	 * 
-	 * <pre>
-	 * Dictionary d = new Hashtable();
-	 * d.put(&quot;cn&quot;, new String[] {&quot;a&quot;, &quot;b&quot;, &quot;c&quot;});
-	 * </pre>
-	 * 
-	 * d will match {@code (cn=a)} and also {@code (cn=b)}
-	 * 
-	 * <p>
-	 * A filter component that references a key having an unrecognizable data
-	 * type will evaluate to {@code false} .

+ * <p>
+ * The {@code Condition} service interface is a marker interface designed to
+ * address this issue. Its role is to provide a dependency that can be tracked.
