There are at least two options:

  * Go back to older xerces :-)
  * Check presense of the new xerces using reflection,
    and make sure code works with both old xerces and new one.

Yes, I have. I won't be able to deploy Cocoon with this new Xerces for some time 
till all containers, servers are upgraded to it. For some people, it could be 
1/2 year to year. Cocoon 2.1 must continue to work on older Xerces releases to 
ensure compatiblity with existing infrastructure a lot of folks out there have. 
Not everybody can replace vital JDK parts on a whim.

If you see value in supporting new xerces, please use reflection.
