A name in an xml document. Names are composed of two components. A (possibly-empty) namespace along with a local name. Names are unique and will be represented with singleton objects. This means that equality can be computed very quickly with a simple reference equality check. In the case of <foo> the namespace will be empty and the local name will be "foo". In the case of <ns0:foo xmlns:ns0="http://foo.com"/> the namespace will be "http://foo.com" and the local name will be "foo". XML names also have an 'expanded' form that is equivalent to the non-standard QName format used by java. Specifically, it has the form: "{" + getNamespace() + "}" + getLocalName(). This can be used when interoping with other java XML libraries.
