this created an incompatibility with old XML save files,
old versions of midas cannot load new XML save files,
variable types have changed i.e. from "INT" to "INT32".

it would have been better if XML save files kept using the old names.

now packages that read midas XML files also need updating.

specifically, in ROOTANA:
- the old TVirtualOdb/XmlOdb.cxx (no longer used, deleted),
- mvodb/mxmlodb.cxx
