Namespace generated XSD and add missing attributes

This adds two things to the XSD (and the RNC file and options.md):
* attributes previously missing because of a bug in the conversion
  script
* a name space (https://cdds.io/config)

Adding the name spacing requires a different set of attributes at the
top of a configuration file, which in turn need to be ignored by the
configuration parser, and which should be reflected in the configuration
example in the README.
