Since there is technically no governing schema to cover  
CustomAttributes, I changed the validation instructions to "skip" from  
"strict".  This eliminated these types of processing errors.  This  
change should propagate sometime tonight.  Sample.ome now validates  
properly.

I think this still needs to be fixed - haven't looked into this.

The wildcard specification wasn't quite correct in the CA schema.  It  
should work now.

Changes to the main branch should propagate to the main schema (i.e.  
the "official" one on the web) every night.  Committing it to a branch  
won't really do anything.  Did you update documentation in OME-WEBSITE?

Its well nigh impossible second-guessing validation problems.  If there  
are documents that don't validate, please simplify them as much as  
possible and attach them to a bug report in Bugzilla.

The definitive XML Validator is http://www.w3.org/2001/03/webdata/xsv,  
though validation should pass in TurboXML as well.
