Since the <unprefixed> element does not have a prefix, it is in the
default namespace. The default namespace that is in-scope at the
<unprefixed> element is the DOC_NAMESPACE. Therefore the schema
validator should validate the <unprefixed> element against the element
declaration for the {DOC_NAMESPACE}unprefixed element, which will be a
top-level (global) declaration.
