[M4IF Technotes] About Advanced Simple Profile tools

[Rob Koenen]

Don't ask me to devise a testing strategy for you :-)
There are conformance bitstreams for ASP but I am unsure
about their general availability. Perhaps someone else
on the list knows if they are already available or when
they will be if not now.
In the future, M4IF will be able to help you with bistreams,
but that is of little help for you now.
Good luck,
Rob
