5. We will keep copies of the specifications we use under SCM in the 
sourceforge project that hosts the schemas. This is the only way to 
ensure that the specifications will remain available and consistent.

It is worth noting that despite the fact that WSDM is based on WSRF 
1.2-draft0.1, not all the relevant XSD files are where they need to be 
for that spec, ws-basefaults has disappeared. By hosting locally we 
avoid this problem.

We do have to patch the XSD/WSDL files so that they import files 
locally, rather than try and do it from remote (potentially nonexistant) 
locations. This leads to an interesting problem, the oasis copyright:

--------
This document and translations of it may be copied and furnished to 
others, and derivative works that comment on or otherwise explain it or 
assist in its implementation may be prepared, copied, published and 
distributed, in whole or in part, without restriction of any kind, 
provided that the above copyright notice and this paragraph are included 
on all such copies and derivative works. However, this document itself 
may not be modified in any way, such as by removing the copyright notice 
or references to OASIS, except as needed for the purpose of developing 
OASIS specifications, in which case the procedures for copyrights 
defined in the OASIS Intellectual Property Rights document must be 
followed, or as required to translate it into languages other than English.
--------

It is unclear whether fixing the XSD/WSDL files so that they work 
constitutes "derivative works to assist in implementation" or "a 
modification". I am requesting clarification on this matter.

Sigh.
