/**
* Represents an XML tag name (and attributes for start tags.)

* This object is used so reduce the number of method call parameters
* among unmarshallers.
*
* An instance of this is expected to be reused by the caller of
* {@link XmlVisitor}. Note that the rest of the unmarshaller may
* modify any of the fields while processing an event (such as to
* intern strings, replace attributes),
* so {@link XmlVisitor} should reset all fields for each use.
*
* <p>
* The 'qname' parameter, which holds the qualified name of the tag
* (such as 'foo:bar' or 'zot'), is not used in the typical unmarshalling
* route and it's also expensive to compute for some input.
* Thus this parameter is computed lazily.
