We discussed this at the recent F2F in relation to issue 4 which raises 
the question of what a receiver should do on receipt of a message 
containing a PI or DTD. I have an pending action to re-raise this issue 
- consider it raised !

There seems to be two opinions on the subject of DTDs and PIs:

(i) Allowing them increases complexity and doesn't bring any particular 
benefit, the only compelling argument for allowing PIs was so that a 
stylesheet could be associated with a message for human viewing.

(ii) Adding them doesn't add much to the complexity, they are part of 
XML so we should allow them.

My original suggestion for resolution of issue 4 was to retain their 
current status (i.e. not allowed) and add text requiring a SOAP 
processor to generate a fault when a message containing one was received.

Others felt that if present they should be ignored but this might prove 
difficult in the case of DTDs with current parsers.

Discussion ?

Regards,
Marc.
