24  * A QName class for dealing with XML Qualified Names; basically,
25  * a namespace and a localpart.
26  *
27  * This class is intended solely for those who for some reason can't
28  * use javax.xml.namespace.QName. See that class for documentation.
29  * Remember that prefix is not part of equals or hashCode.
