[jdev] xml processing question

Hi all,

I've come across something which seem like a possible issue w.r.t. xml
processing
for xmpp implementations.

The first is that rfc1390, sec 11.1 (restrictions on xml) states that

1) With regard to XML generation, an XMPP implementation MUST NOT inject
into an XML stream any of the following
[ dtds and stuff]

2) With regard to XML processing, if an XMPP implementation receives such
restricted XML data, it MUST ignore the data
My question is what happens when a server receives xml with craziness like
embedded dtds but, having
ignored such restricted data, it decides it must pass the message on to
another server.  How can a server fullfill both
1 and 2 above?  What is generally done in these cases?

Best
