That would have been sufficient, except that many questions occur in XQuery
that did not occur in XML namespaces as part of an XML document.
XQuery needs to be able to declare namespace prefixes globally, and the
interactions between these global interactions and the xmlns attributes in
element constructors had to be defined. Can two global namespace
declarations declare the same prefix? Can an xmlns attribute redefine a
prefix previously assigned? Also, namespace prefixes can be used in
expressions that occur within curly braces in an element - can namespace
prefixes defined with namespace attributes in element constructors be used
in these expressions? These kinds of questions had to be answered, which is
why the given section of the XQuery document exists.
