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.
