  in the regexp engine on transition changes. The fact that it's not
easy to find out does not mean it doesn't work.

  Well that's not even well-formed ! Could you please follow the 
guidelines for getting help !!!! 
  http://xmlsoft.org/bugs.html
 I *really* do not see why trying with an example and if it fails with
xmllint --schema *then* report the problem is too hard to follow !

  that's different from min/max ... that does work at the Relax-NG level.
I think that should work with Schemas too. Try it instead of asking 
whether this would work !!!
  I a nutshell do your part of the job as asked on the web page about getting
help, and then I will do my part of the job !
