public class QName

extends java.lang.Object

implements java.io.Serializable

Class to represent a qualified name: "The name of an internal XSLT object, specifically a named template (see [7 Named Templates]), a mode (see [6.7 Modes]), an attribute set (see [8.1.4 Named Attribute Sets]), a key (see [14.2 Keys]), a locale (see [14.3 Number Formatting]), a variable or a parameter (see [12 Variables and Parameters]) is specified as a QName. If it has a prefix, then the prefix is expanded into a URI reference using the namespace declarations in effect on the attribute in which the name occurs. The expanded name consisting of the local part of the name and the possibly null URI reference is used as the name of the object. The default namespace is not used for unprefixed names."
