Qualified Names  
[prefix:]local_part

A qualified name is an element or attribute name that is associated with an XML namespace. There are three possible types of qualified names:

  • Unprefixed element names that are contained within the scope of a default namespace declaration

  • Prefixed element names

  • Prefixed attribute names

Unlike unqualified names, qualified names are considered the same only if their namespace URIs (from their namespace declarations) and their local parts match.
