Definition of "\w" multi-character escape

In the XML Schema: Datatype Proposed Recommendation appendix F, the
definition of the "\w" multi-character escape reads:

[#x0000-#x10FFFF]-[\p{P}\p{S}\p{C}] (all characters except the set of
"punctuation", "separator" and "control" characters

This would appear to imply that \p{S} is the category escape for "separator"
chars, whereas it is actually "symbol" chars.  I think the correct text
should probably read:

[#x0000-#x10FFFF]-[\p{P}\p{Z}\p{C}] (all characters except the set of
"punctuation", "separator" and "control" characters

but then, I'm an almost complete newbie ;-)

cheers
