Makes a lot of sense.

I'm not sure we have to annotate particular arguments. At least, not for 
providing documentation. Maybe for things like default parameters.

A Doxygen-style snippet should be enough:
  This method makes the window wobble and flip.
  \param  msec      the time in milliseconds the window should wobble

The only thing I worry about is memory consumption. Documentation could 
make the XML introspection of a given interface or node quite long. And 
caching all that may prove to be too much. If we decide to go this way, 
I'd like it to be standardised, so I could discard unnecessary data.

(The Qt bindings right now introspect when needed and cache the data for 
the duration of the connection)
