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

| * <p> |
| * 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. |
