Ok,

So at this point the host is responsible for the GUI and the file dialog.
If thats the case I'm finding it harder to see why a wildcard would be
needed in a paramter ?

If the  host presents the file dialog to the user, and gets a file name to
be passed to the GUI then that will be a fully qualified file name ?

I am finding it hard to see why a plugin would pass file name to the host
with a wild card in it ?  The only time may be to say "I can handle files of
type X,Y and Z" but that wouldn't better handled at instantiation ?  Is
there a use case example?

As for wildcards, which do we support , if any? Do we support the rather
limted set that windows supports or the full set that most Unix variations
allow.  And that then begs the question of how a Windows host will handle a
request containing the Unix type wildcards ?

Ron suggested we  use URL type for file names.  However (without looking at
the specs) I don't think that wildcards have a special meaning in a URL
which will mean it's up host to parse it into OS specific terms ?

I hope I'm not beating this one too much to death
