I suspect not ... I discovered a bug in that a few days ago, when I 
noticed that a parse of
an invalid document worked.  This bug is fixed in the CVS repository.

NB. to validate, the parse must be able to find the DTD.  It does this 
by loading the DTD
from a file, and you probably need to override the loadEntity:at: method 
to return the
filename to be used (or there is builtin support to look for DTDs 
locally in the DTDs
subdirectories of the bundle resources of applications, where the name 
of the DTD file
is the entity URL with all path separators replaced by underscores).
