Why?  You can always write xmlRoot[xml.name], if xml.name is assigned the
name index you want to use and it's not any different from xmlRoot[true]
that you proposed.

Nope.  Try

    print({} == {})

Boolean true or false can be used.  You could also use the empty string ""
(which is also not a valid XML name.)
