[m-users.] XML library: highly ambigious overloadings

[Volker Wysk]

Hi

Following Zoltan's explanation, I've managed it to compile, like this:

main(!IO) :-
    Text = "bla.",
    pstate(mkEntity(Text), mkEncoding(utf8), init, !IO),
    finish(Res, !IO).

But I get a lot of warning messages about highly ambiguous overloading in
the xml.parse module. I've attached the error output. The ambigious names
should probably be qualified.

Cheers,
Volker
