For those wondering, the real power comes when you use the support for functional indices in combination with XML. You can create indexes on fragments of the XML and perform some very nice queries against large sets of XML documents. Hey, I'm not advocating this, but if you've got a ton of XML data and also an existing swath of relational, it's hard to map them onto each other without this level of in-database support. It's also nice because it supports partial updates of the XML documents do that concurrent updates don't clobber each other during some kind of horrible read-then-write dance. It would be really great to have first class JSON support at the level of this XML support built-in though. Certainly could convince some potential MongoDB converts to stay put.
