That SAX would return the element type name in localName.

local names

local names

Haven't implemented a parser

Didn't participate.

NOTE:

I believe that the namespaces spec states that the local name is always
non-null. In particular, the definition of a QName has an optional
prefix:

   QName ::= (Prefix ':')? LocalPart

and states that, "[Definition:] The LocalPart provides the local part of
the qualified name."

If there was no such thing as a local name when namespaces weren't used,
then it seems that the spec would not explicitly cover the case where no
prefix is used and there is no default namespace (see section 5.2). That
is, it would require either a prefix or a default namespace and it would
explicitly state that documents containing unprefixed names in the
absence of a default namespace would be considered non-conformant.
