When I read this for the first time I assumed that local names would always
be present (when namespaces are enabled).  I can see now that the clause
"(if one is specified, both must be)" is ambiguous if the namespace URI is
empty, but I still think of an empty URI string as providing the namepace
URI - which happens to be empty.

The ElCel SAX Driver always provides a local name.  If the namespace URI is
empty (i.e. there is no default namespace), then the localName is equal to
the qName.  When namespace processing is disabled, we still provide a
localName and a qName which are identical.
