I thought this was done "behind the scenes" ? For our part we are looking with 
interest at what comes out of the mix in terms of XML & databases over the next 18 
months or so from the "big 3" - Oracle, SQL Server & DB2.

If we get these facilities "natively" from U2 (or another mv player), great. If not, 
then we have "Plan V" :-)
