+/**
+ * This class implements an HTML5 parser that exposes data through the DOM 
+ * interface. 
+ * 
+ * <p>By default, when using the constructor without arguments, the 
+ * this parser treats XML 1.0-incompatible infosets as fatal errors. 
+ * This corresponds to 
+ * <code>FATAL</code> as the general XML violation policy. To make the parser 
+ * support non-conforming HTML fully per the HTML 5 spec while on the other 
+ * hand potentially violating the DOM API contract, set the general XML 
+ * violation policy to <code>ALLOW</code>. This does not work with a standard 
+ * DOM implementation. Handling all input without fatal errors and without 
+ * violating the DOM API contract is possible by setting 
+ * the general XML violation policy to <code>ALTER_INFOSET</code>. <em>This 
+ * makes the parser non-conforming</em> but is probably the most useful 
+ * setting for most applications.
+ * 
+ * <p>The doctype is not represented in the tree.
+ * 
+ * <p>The document mode is represented as user data <code>DocumentMode</code> 
+ * object with the key <code>nu.validator.document-mode</code> on the document 
+ * node. 
+ * 
+ * <p>The form pointer is also stored as user data with the key 
+ * <code>nu.validator.form-pointer</code>.
