/**
*
* most extremely very prototypical skeleton schema converter<br/>
* TODO: we may want to simply generate from autoclasses rather than from the existing schema...<br/>
* or forget the walker pattern and simply loop^
* the old implementattion was obsolete this implementation extracts more data from the xml schema that can be injected into the json schema
*
* Schema policies: Retain substitutiongroups (elements of resource/parameter)
* make local elements local - there is only one remaining element definition
* make attribute definitions local but retain global attribute type definitions - think about unique enumerations -probably local
