  well, at the time of the error, all libxml2 had left from the Schemas
content model is a compiled automata. Sometimes that automata can be
reserialized as a string making sense to a human, we don't have an API for
this (yet that could be added). It's also sometime hard to find out what
exactly generated the error, seems the content model wrong is for an element
starting line 3 but the error shows up line 18.
  Error reporting can certainly be improved, but it's usually not trivial to
provide back the "useful" information.
