  The loader should not parse. It should return the input to parse, in
python the string c.f. the examples.

  The context is passed in the callback to be able to identify what is
requesting that loading. The parser at that point is in the middle of 
parsing a document. You definitely cannot reuse it to parse something 
different there. Basically in python except for identification you must
not try to use it.
