Henry:

We are in a meeting discussing the adoption of the W3C xlink.xsd across the OGC XML schemas. 
The question has arisen about 
(a) timing of when/if the W3C xlink.xsd schema can be considered stable 
 - we notice that the one currently posted at http://www.w3.org/1999/xlink.xsd is different to the version inline in the current xlink 1.1 working draft
 - I guess this will change when the new WD is issued, but this seems slow coming?
(b) what the status of the schema is 
 - I guess it is an Appendix to xlink 1.1, but this is still some way (years?) from reaching 'recommendation' status 

The concern is that, until W3C hosts something stable, there are still (at least) two different schemas for xlink out in the wild - one from OGC, one from OASIS. Because these are different it makes any schemas that have dependencies on both OGC and OASIS broken. But neither OGC nor OASIS have any interest in initiating a harmonization process that pre-empts the W3C schema, particular since W3C owns the namespace!  

We're feeling a bit hamstrung, and could use some guidance from W3C.
