XML/SQL, XQuery and XML Databases ...

The big commercial RDBMS's (Oracle, DB2, MS SQL Server) have all added serious support for XML in their databases. So, one could store large XML docs and query via SQL/XML or XQuery. It appears that they have been labelled "hybrid databases". (relational and document-centric). There are commercial "native XML" databases such as MarkLogic that have gained decent traction in the marketplace as well. This is big.

I did'nt see anything similiar with MySQL. As far as I could figure out, the 6.x release does not contain anything along those lines. Similarily there does'nt seem to be much going on with Postgres.

At this time there don't seem to be serious alternatives in the open-source world. The current open-source implementations (exist, sedna ...) are not quite ready for prime-time it appears. (not stable enough, don't seem to scale, weak protocol support, weak api's ).

Anyone else care to comment on this ?. Any folks at MySQL (PM types) that would like to enlighten us ?.
