I think this is a cool thing, a few thoughts:

* we should make it possible to make metadata show up as embedded
explicit mixed content (attributes or elements?) with a document
stored in the database if we need to serialize document.

* there maybe versioning considerations to think through with metadata

* I do feel that considering a new metadata axis is useful but we need
to be careful e.g. is it being proposed that we will have a metadata
namespace for this stuff
