aoqi@0	35	* Represents an XML tag name (and attributes for start tags.)
aoqi@0	36	*
aoqi@0	37	* <p>
aoqi@0	38	* This object is used so reduce the number of method call parameters
aoqi@0	39	* among unmarshallers.
aoqi@0	40	*
aoqi@0	41	* An instance of this is expected to be reused by the caller of
aoqi@0	42	* {@link XmlVisitor}. Note that the rest of the unmarshaller may
aoqi@0	43	* modify any of the fields while processing an event (such as to
aoqi@0	44	* intern strings, replace attributes),
aoqi@0	45	* so {@link XmlVisitor} should reset all fields for each use.
aoqi@0	46	*
aoqi@0	47	* <p>
aoqi@0	48	* The 'qname' parameter, which holds the qualified name of the tag
aoqi@0	49	* (such as 'foo:bar' or 'zot'), is not used in the typical unmarshalling
aoqi@0	50	* route and it's also expensive to compute for some input.
aoqi@0	51	* Thus this parameter is computed lazily.
