[Simple] Presence Relax NG schemas

[Jari Urpalainen <jari.urpalainen at nokia.com>]

Hi all!

I have submitted a draft
<http://www.ietf.org/internet-drafts/draft-urpalainen-simple-presence-relaxng-00.txt> (targeted as informational). This memo describes PIDF + extension schemas written with the Relax NG schema language. These were produced because with the W3C schemas it is not possible to write reasonable combination presence schemas doing on-the-fly validation (because of the paranoid UPA constraint specified in the appendix H of W3C structures spec). So these are meant for publishers of presence information and the rules given in these schemas are thus stricter than the W3C schemas. Therefore, instance documents that validate with these shall also validate with the W3C schemas. The set incluces schemas for PIDF, datamodel, RPID, CIPID and CAPS. There are still some minor differencies between these and PIDF extension schemas (some "last minute" changes in I-D's). So these are not meant to replace W3C schemas, they are just produced to decrease interoperability problems with "real" implementations. W3C Schema 1.1 spec may eventually have a proper wildcard definition etc., but before it happens these schemas can be utilized.

Any comments ? 
Jari
