I can certainly imagine cases for processing where having the field names and other metadata up front (maybe add type info, nullable, etc instead of just "undefined") would be useful.
here's another question: If the intention is to use field names as (local) tag names, how will you handle the case where the field name isn't a valid XML name? Of course, one could do some sort of mapping (replace illegal chars with "_", for example) but then you can't be 100% certain that you haven't generated a collision, I should think. andrew ----- Original Message ----- From: "Steve Wampler" <[EMAIL PROTECTED]> To: "mlw" <[EMAIL PROTECTED]> Cc: "Hannu Krosing" <[EMAIL PROTECTED]>; <[EMAIL PROTECTED]>; "Postgres-hackers" <[EMAIL PROTECTED]> Sent: Tuesday, April 01, 2003 12:40 PM Subject: Re: [HACKERS] PostgreSQL and SOAP, suggestions? > Out of curiousity, what is the purpose of putting the qry:ROWSET > description into the message at all (header or not)?
