This is the correct interpretation I believe.


http://www.w3.org/TR/xmlschema-2/#regexs

says

  A single XML character is a ·character range· that identifies the set
  of characters containing only itself. All XML characters are valid
  character ranges, except as follows:
  ...
  The - character is a valid character range only at the beginning or
  end of a ·positive character group·. 



which means that you can (should be able to) use - to mean itself as the
last character in a [] group.
