I will try to answer one of these:

They are valid.  See Appendix F in the Datatypes document [1].  These are in
a group called multi-character escapes. (Right near the end of Appendix F).
\i represents initial name charcters as defined by XML 1.0 second edition
and \c represents name characters.

BTW simpleType conformance isn't complete in XSV.  SO this pattern may not
be checked-- though Henry could give a more definitive answer.
