Hi Jonathan, I considered it but decided our requirements were simpler. I am settling on a solution that is similar in design to the WSRT specification (W3 Submission): <http://www.w3.org/Submission/WSRT> See section 3.4 on PUT operation on how fragments may be used in partial insert, update and delete operations. This spec looks very promising but is not yet a REC. Also I wish they used type substitution to remove mixed=true types which seem like a questionable design choice. Thanks all for your helpful suggestions.
