Thanks Cameron,

I have added the following text to the Graduation Checklist 
under the Copyright and License section:

* One outstanding issue with OGC schemas: The OGC schemas are included 
in pycsw to validate incoming XML requests. The OGC schemas are licensed 
under the terms of the OGC Document Notice or under the terms of OGC 
Software Notice according to the legalfaq 
(http://www.opengeospatial.org/ogc/legalfaq#DTD): "Schemas (and DTDs) 
are frequently part of our specifications and seemingly fall under the 
document copyright terms. However, as long as you do not use the same 
formal namespace or public identifier to identify that modified OGC 
schema/DTD (which might confuse applications), you may treat the 
schema/DTD under the software terms. This means that you are permitted 
to make a derivative or modified OGC schema/DTD, but even under the 
software terms you are obligated to include/retain the OGC copyright 
notice. We further appreciate a couple sentences regarding who made the 
modifications, when, and what changes were made in the original DTD -- a 
common software documentation practice." This was found incompatible 
with the Debian Free Software Guidelines (DFSG), which strictly 
considers schemas to fall under the document copyright terms (not free 
to modify), thus pycsw package was rejected from Debian. On the other 
hand, since pycsw only uses the schemas for validation and does not 
publish them online, we use the second clause of the OGC legalfaq and we 
consider schemas to fall under the software copyright terms 
(modifications are allowed). We have included the OGC copyright notice 
and a note of how we use the OGC schemas 
Furthermore, pycsw has been accepted in openSUSE, Fedora, Ubuntu and 
OSGeoLive without any legal objections. For more information see:

   - https://github.com/geopython/pycsw/issues/306
   - https://github.com/geopython/pycsw/pull/313
   - http://lists.osgeo.org/pipermail/standards/2015-February/000842.html
   - http://www.opengeospatial.org/ogc/document
   - http://www.opengeospatial.org/ogc/software

I hope the above addresses the issue until a better solution comes from 
the OSGeo, OGC, DebianGIS discussion.
