I don't understand.  What i've done is exactly to remove double
definitions which were in obr.xml files.

Nobody has ever said they consist in a comma separated list of service classes.
The way I've implemented the generation is exactly what you're asking for.

Export-Service:  foo.bar.Interface;availability:=optional;x=v

You're right about the filters, I haven't put those on the header, but
I'll fix that asap.

Unless you can prove that there are some informations that can't be
put on those headers,
I think it really simplifies the role of the tooling to not have to
dig into multiple different formats.
