Good. Not tolog 1.0 'standard' conform, but it works. ;)

No, if you look into the tolog parser source (tolog.g), you'll notice
that the parser expects "::" as namespace delimiter. I don't know the
reason for it, maybe an older tolog version uses "::" for the
namespace.

You can try to change the line 501 - 502 from
    prefixedident :
      (NAME DBLCOLON) => prefix:NAME DBLCOLON ref:NAME

to
    prefixedident :
      (NAME COLON) => prefix:NAME COLON ref:NAME

and try compile the grammar.
I don't know if it works or if has (negative) side effects.

It's a bug. You can report it here:
<https://sourceforge.net/tracker/?group_id=27895&atid=391879>

Yeah. This is somewhat related to the "String bug", reported here:
<https://sourceforge.net/tracker/index.php?func=detail&aid=1308137&group_id=27895&atid=391879>

The URI / String handling of the parser is buggy.

I tried to provide some quick fixes / patches but the whole thing
requires more time.

Best regards,
Lars
