XPath's fn:matches
  http://www.w3.org/TR/xpath-functions/#func-matches
now has this exciting thing to say about collations:
[[
Note:

Regular expression matching is defined on the basis of Unicode code
points; it takes no account of collations.
]]

which means we have no functions that require collations. The sentence
[[
The collation is defined in section 7.3.1 Collations.
]]
needs to go away. I don't think we need to repeat the note.

Do I need a vote on this? or can I strike it before the publication?
