There are no actual usage guidelines, however I recommended using 
"fixed" value attributes on a schema or DTD rather than use Namespaces. 
  This would cut down on th eactual size and processing overhead of the 
business payloads unless someone decided to do a validating parse.  An 
unvalidated parse would simple ignore the [ DTD | schema ] and process 
the message.

The UID's would be used mainly for retreiving semantic meaning in order 
to map from one message to another.
