libvorbis - non-free content?

[Martin Steghöfer]

Hi all,

I've noticed the lintian warning 
"license-problem-non-free-RFC-BCP78.html" [1, 2] in our package 
libvorbis with respect to the file "doc/rfc5215.txt" (and probably 
"doc/rfc5215.xml", too, although lintian doesn't mention it). This is 
because the IETF's RFC documents aren't generally released under a free 
license. In the particular case of RFC5215, however, I've found the 
following paragraph [3]:

11.  Copying Conditions

    The authors agree to grant third parties the irrevocable right to
    copy, use, and distribute the work, with or without modification, in
    any medium, without royalty, provided that, unless separate
    permission is granted, redistributed modified works do not contain
    misleading author, version, name of work, or endorsement information.


This makes me consider it free content anyway.

What do you think? Do you see it the same way? Should we override the 
lintian error? Or should we consult with an expert on this?

Cheers,
Martin
