/**
 *  An interface to an object that is able to build, or augment, a DOM tree 
 * from various input sources. 
 * <p> <code>LSParser</code> provides an API for parsing XML and building the 
 * corresponding DOM document structure. A <code>LSParser</code> instance 
 * can be obtained by invoking the 
 * <code>DOMImplementationLS.createLSParser()</code> method. 
 * <p> As specified in [<a href='http://www.w3.org/TR/2004/REC-DOM-Level-3-Core-20040407'>DOM Level 3 Core</a>]
 * , when a document is first made available via the LSParser: 
 * <ul>
 * <li> there will 
 * never be two adjacent nodes of type NODE_TEXT, and there will never be 
 * empty text nodes. 
 * </li>
 * <li> it is expected that the <code>value</code> and 
 * <code>nodeValue</code> attributes of an <code>Attr</code> node initially 
 * return the <a href='http://www.w3.org/TR/2004/REC-xml-20040204#AVNormalize'>XML 1.0 
 * normalized value</a>. However, if the parameters "<a href='http://www.w3.org/TR/DOM-Level-3-Core/core.html#parameter-validate-if-schema'>
 * validate-if-schema</a>" and "<a href='http://www.w3.org/TR/DOM-Level-3-Core/core.html#parameter-datatype-normalization'>
 * datatype-normalization</a>" are set to <code>true</code>, depending on the attribute normalization 
 * used, the attribute values may differ from the ones obtained by the XML 
 * 1.0 attribute normalization. If the parameters "<a href='http://www.w3.org/TR/DOM-Level-3-Core/core.html#parameter-datatype-normalization'>
 * datatype-normalization</a>" is set to <code>false</code>, the XML 1.0 attribute normalization is 
 * guaranteed to occur, and if the attributes list does not contain 
 * namespace declarations, the <code>attributes</code> attribute on 
 * <code>Element</code> node represents the property <b>[attributes]</b> defined in [<a href='http://www.w3.org/TR/2004/REC-xml-infoset-20040204/'>XML Information Set</a>]
 * . 
 * </li>
 * </ul>
 * <p> Asynchronous <code>LSParser</code> objects are expected to also 
 * implement the <code>events::EventTarget</code> interface so that event 
 * listeners can be registered on asynchronous <code>LSParser</code> 
 * objects. 
 * <p> Events supported by asynchronous <code>LSParser</code> objects are: 
 * <dl>
 * <dt>load</dt>
 * <dd>
 *  The <code>LSParser</code> finishes to load the document. See also the 
 * definition of the <code>LSLoadEvent</code> interface. </dd>
 * <dt>progress</dt>
 * <dd> The 
 * <code>LSParser</code> signals progress as data is parsed.  This 
 * specification does not attempt to define exactly when progress events 
 * should be dispatched. That is intentionally left as 
 * implementation-dependent. Here is one example of how an application might 
 * dispatch progress events: Once the parser starts receiving data, a 
 * progress event is dispatched to indicate that the parsing starts. From 
 * there on, a progress event is dispatched for every 4096 bytes of data 
 * that is received and processed. This is only one example, though, and 
 * implementations can choose to dispatch progress events at any time while 
 * parsing, or not dispatch them at all.  See also the definition of the 
 * <code>LSProgressEvent</code> interface. </dd>
 * </dl>
 * <p ><b>Note:</b>  All events defined in this specification use the 
 * namespace URI <code>"http://www.w3.org/2002/DOMLS"</code>. 
 * <p> While parsing an input source, errors are reported to the application 
 * through the error handler (<code>LSParser.domConfig</code>'s "<a href='http://www.w3.org/TR/DOM-Level-3-Core/core.html#parameter-error-handler'>
 * error-handler</a>" parameter). This specification does in no way try to define all possible 
 * errors that can occur while parsing XML, or any other markup, but some 
 * common error cases are defined. The types (<code>DOMError.type</code>) of 
 * errors and warnings defined by this specification are: 
 * <dl>
 * <dt> 
 * <code>"check-character-normalization-failure" [error]</code> </dt>
 * <dd> Raised if 
 * the parameter "<a href='http://www.w3.org/TR/DOM-Level-3-Core/core.html#parameter-check-character-normalization'>
 * check-character-normalization</a>" is set to true and a string is encountered that fails normalization 
 * checking. </dd>
 * <dt><code>"doctype-not-allowed" [fatal]</code></dt>
 * <dd> Raised if the 
 * configuration parameter "disallow-doctype" is set to <code>true</code> 
 * and a doctype is encountered. </dd>
 * <dt><code>"no-input-specified" [fatal]</code></dt>
 * <dd> 
 * Raised when loading a document and no input is specified in the 
 * <code>LSInput</code> object. </dd>
 * <dt>
 * <code>"pi-base-uri-not-preserved" [warning]</code></dt>
 * <dd> Raised if a processing 
 * instruction is encountered in a location where the base URI of the 
 * processing instruction can not be preserved.  One example of a case where 
 * this warning will be raised is if the configuration parameter "<a href='http://www.w3.org/TR/DOM-Level-3-Core/core.html#parameter-entities'>
 * entities</a>" is set to <code>false</code> and the following XML file is parsed: 
 * <pre>
 * &lt;!DOCTYPE root [ &lt;!ENTITY e SYSTEM 'subdir/myentity.ent' ]&gt; 
 * &lt;root&gt; &amp;e; &lt;/root&gt;</pre>
 *  And <code>subdir/myentity.ent</code> 
 * contains: 
 * <pre>&lt;one&gt; &lt;two/&gt; &lt;/one&gt; &lt;?pi 3.14159?&gt; 
 * &lt;more/&gt;</pre>
 * </dd>
 * <dt><code>"unbound-prefix-in-entity" [warning]</code></dt>
 * <dd> An 
 * implementation dependent warning that may be raised if the configuration 
 * parameter "<a href='http://www.w3.org/TR/DOM-Level-3-Core/core.html#parameter-namespaces'>
 * namespaces</a>" is set to <code>true</code> and an unbound namespace prefix is 
 * encountered in an entity's replacement text. Raising this warning is not 
 * enforced since some existing parsers may not recognize unbound namespace 
 * prefixes in the replacement text of entities. </dd>
 * <dt>
 * <code>"unknown-character-denormalization" [fatal]</code></dt>
 * <dd> Raised if the 
 * configuration parameter "ignore-unknown-character-denormalizations" is 
 * set to <code>false</code> and a character is encountered for which the 
 * processor cannot determine the normalization properties. </dd>
 * <dt>
 * <code>"unsupported-encoding" [fatal]</code></dt>
 * <dd> Raised if an unsupported 
 * encoding is encountered. </dd>
 * <dt><code>"unsupported-media-type" [fatal]</code></dt>
 * <dd> 
 * Raised if the configuration parameter "supported-media-types-only" is set 
 * to <code>true</code> and an unsupported media type is encountered. </dd>
 * </dl> 
 * <p> In addition to raising the defined errors and warnings, implementations 
 * are expected to raise implementation specific errors and warnings for any 
 * other error and warning cases such as IO errors (file not found, 
 * permission denied,...), XML well-formedness errors, and so on. 
 * <p>See also the <a href='http://www.w3.org/TR/2004/REC-DOM-Level-3-LS-20040407'>Document Object Model (DOM) Level 3 Load
