handling a non free test databank

[Sébastien Barthélemy <barthelemy@crans.org>]

Hello,

I'm still working on the collada-dom package, and I noticed that
the source tarball contains 3d assets that are licensed under
Creative Commons Attribution Noncommercial Share Alike license
(no version).

I believe this license is not DFSG-compatible. These files are
part of the software itself, but are part of its regression tests.

Should I repackage a dfsg version of the source without these
files? (I think so, but would welcome a confirmation).

If so, how should I handle the tests? Should I automate the
 download (I would use svn export) of the test data bank?
If sso, when? At libcolladadom-dev install? Within the
dh_override_auto_test target?

Or should I create a dedicated libcolladadom-testdatabanck package
to spare sourceforge bandwidth?
