  Hum, no. At the moment, the schemas APIs are minimal, this makes sense
because the implementation is not considered complete.
  I didn't try to implement Schemas or Type content lookup, it may
not be trivial to design such API, and honnestly I didn't studied 
any of the APIs provided by other toolkits. It sounds unlikely I will
get the time needed for this, doing this isn't a simple patch, such
API need some thought on design, so it's not like getting a simple 
function implemented and applying a patch. However you're not the only
one interested and if there is enough people looking at this then
maybe this can be designed and build.
