xsd:QName

The type xsd:QName represents an XML namespace-qualified name. A xsd:QName value consists of a prefix and a local part, separated by a colon, both of which are NCName values. The prefix and colon are optional, but if they are not present, it is assumed that either the name is namespace-qualified by other means (e.g., by a default namespace declaration), or the name is not in a namespace.
