Do you mean the extension functions/elements as in the specification? We
do plan to support these, it's a must; the plan is to let the user set
up a callback to receive calls to extension functions in a particular
namespace. Now these functions will probably need full DOM-like access
to the XML trees; for this, they will have a new C API (seems better
than direct access to the "real" object representation). I'm not sure
about how to deal with the different types yet.
