java.lang.Object | +--net.sf.saxon.value.Value | +--net.sf.saxon.value.AtomicValue | +--net.sf.saxon.value.QNameValue
A QName value. This implements the so-called "triples proposal", in which the prefix is retained as part of the value. The prefix is not used in any operation on a QName other than conversion of the QName to a string.
