Are you talking about the method for exchanging the document or the
actual business data itself.  If it is the business data itself,  I
think that the correct procedure for CPA terms is that the requesting
company MUST agreee to the data requirements of the Receiving company. 
Please allow me to explain:

A company published their capabilities in their CPP.  One of their
capabilities MAY be to provide XML to XML (or other formats)
transformation.  If they only have a place to publish what businesss
information they need (eg. - 


it must be assumed <IMHO> that any data transformation must be done by
the requesting company before the data is sent.  THe Requesting company
knows that they can (or can't) transform their own data (eg. an VISA XML
invoice) into the required data specification.  THe receiving company
would have to be queried to ask if they have that caability.  This would
be innefficient but may be a possible last step to be able to complete
an automated transaction sequence.

Sorry for all the ramblings lately - looks like I am sort of joining the
TP Group ;-)
