+/**
+ * An Event-Driving, Non-Validating XML Parser with Namespace support.
+ *
+ * A subclass can implement the abstract functions for receiving details
+ * about an xml file as it is parsed. To initate a parse, use the parse()
+ * function.
+ *
+ * <h3>Implementation Notes</h3>
+ * <p>As the parser traverses into an element, it adds it to the linked list
+ * called <tt>elements</tt>. However, <tt>elements</tt> has been pre-filled
+ * with instances of the Element inner class. So in the vast majority of
+ * cases, the pointer current is moved along one, and the values for the
+ * new element are filled into the current object.</p>
+ *
+ * <p>This parser supports all the unicode ranges required by the XML
+ * Specification. However, it is optimised for well-formed ASCII documents.
+ * Documents containing unicode Names and Attributes will take much longer
+ * to process, and invalid documents (badly formed Names or invalid attributes)
+ * will be run through a test on every single unicode character range before
+ * being declared invalid.</p>
+ *
+ * <ul>
+ * <li>Each time the buffer offset <tt>off</tt> is moved, the length
+ * <tt>len</tt> must be decreased.</li>
+ * <li>Each time the buffer length is decreased, it must be checked to make
+ * sure it is >0.</li>
+ * <li><i>error</i> is defined as a Validity Constraint Violation and
+ * is recoverable</li>
+ * <li><i>fatal error</i> is defined as a Well-formedness Constraint
+ * Violation and is not recoverable</li>
+ * </ul>
