Why is -VALIDATE commented out?

["William A. McArthur, Jr" <sa...@ufl.edu>]

I'm using Xalan-J with docbook and It seems that the trasformations 
aren't working because Xalan/Xerces isn't validating the xml which has 
the side effect of id() references not working.

So I checked the source of org/apache/xalan/xslt/Process.java and 
noticed there is code to enable validation but it is commented out. Is 
this code temporarly broken or being phased out by some other method?

Thanks,
