+/**
+ * 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>
+ * <!DOCTYPE root [ <!ENTITY e SYSTEM 'subdir/myentity.ent' ]>
+ * <root> &e; </root></pre>
+ * And <code>subdir/myentity.ent</code>
+ * contains:
+ * <pre><one> <two/> </one> <?pi 3.14159?>
+ * <more/></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.
