Can Jing simply ignore <!DOCTYPE ..> ?

Question:  Can Jing simply ignore <!DOCTYPE ..> ?

I'm using Relax NG with Jing on Solaris and Apple OS X.  Great
stuff.  But here's my little problem/challenge:
 

I've got a set of XML documents (Apple OS X XML keylayout files), old
and new, with

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE keyboard SYSTEM 
"file://localhost/System/Library/DTDs/KeyboardLayout.dtd">

at the top.  When these keylayout files are installed
in OS X, they will get DTD-validated by the system.  (This is done
in the background, with any XML errors being written to obscure log
files, so it's very awkward for people like me who are trying to
develop new keylayout files.

So during development I'd prefer to do
my own validation based on a tighter Relax NG schema and perhaps
other semantic processing.  I have written a Relax NG schema
for these keylayout files, but the <!DOCTYPE ...> declaration
is in the way.

Can I somehow tell Jing to simply ignore the <!DOCTYPE ...>
definition and validate the rest of the document using the
specified Relax NG schema?

Thanks,

Ken
