We can try to get an exception for some of the files, but I'm afraid we won't
get them for all of them. An alternative is to host the problematic test files
some where else and download them while building the plugin. Or do I miss
something?

If so, I would suggest we try to get the exemption for the reference data
streams from the specification and get rid of the dithered photo and the page
from the specification.
In terms of exercised code paths, it is important to have at least one halftone
region, which would be covered by either the photo or the reference streams.
However, should anything go wrong and need debugging, the reference streams are
much easier to handle. Also, I presume the copyright situation is easier to
deal with. The page from the specification, on the other hand, does not seem to
bring something to the table, that isn't already covered elsewhere. (Maybe we
were suffering from a pack rat syndrome here :-)
I could try to talk to the ISO liaison regarding the license. Are there some
terms we could offer that would be acceptable and ASL compatible? Something
like an agreement where the particular files can be used commercially, but only
in conjunction with the particular ASF project?
