python script to run regression tests against the XML Test suite of

* check-xml-test-suite.py: python script to run regression tests
  against the XML Test suite of W3C/OASis
* SAX.c: fixed a validation bug
* parser.c: fixed 3 errors pointed by the test suite
* doc/buildDocBookCatalog: fixed a typo pointed by drake
* python/Makefile.am: fixed a dependendy
