-<p>XML Parser is used to convert XML data to and from the DOM tree structure.The
-end result of the XML parsing is a DOM tree structure. In the case of SMIL,
-the player can use this DOM tree to render the slides. </p>
-<section><title>Introduction</title> <p>In order to parse XML data, an instance
-of the parser must be created. Two types of constructors exist, one type takes
-a <xref href="GUID-F294DC1C-D762-3CF7-BB64-18E742BA6EAA.dita"><apiname>MXMLDtd</apiname></xref> object, while the other does not. If a DTD object
-is supplied, then the parser validates the XML according to that DTD. If no
-DTD class is provided, then no validation takes place. </p> <p>All of the
-constructors take a <xref href="GUID-50F526AD-8471-35DD-8730-9BFB3956537C.dita"><apiname>MMDXMLParserObserver</apiname></xref> parameter. This
-interface is usually implemented by the owning class which then passes itself
-to the parser constructor. This interface exists so that the parser can notify
-its owner when parsing is complete. </p> <p>The way in which the DOM tree
-is used varies depending on the type of XML and even between different clients
-of the same type of XML. Different SMIL players may walk the DOM tree in slightly
-different ways; however several functions are likely to be used by all XML
-clients. </p> </section>
