Description Felix Sasaki 2005-05-25 05:54:07 UTC
(consensus of i18n-core-wg, telecon 25 may 2005):

In sec. 7.6.1 (on Regular Expression Syntax) you should refer to the Unicode
Technical Standard #18 "Unicode Regular Expressions", which describes guidelines
for how to adapt regular expression engines to use Unicode.
Comment 1 Michael Kay 2005-05-25 08:01:24 UTC
Are you suggesting that a normative reference is needed, i.e. that our
specifications don't completely define regular expression semantics without such
a cross-reference? Or are you suggesting that we should provide such a reference
as a kind of historical note explaining how we arrived at our specification?

Comment 2 Ashok Malhotra 2005-05-25 21:57:18 UTC
I took a look at UTS 18.  Its purpose is to teach users how to use Regex's with
collations and warn them of possible difficulties and gotchas.  I agree that
such information may be useful to users of XQuery but I'm not sure we need to do
anything about this.  So, my first reaction is -- do nothing.  The Unicode
Consortium has published this useful document and that's great!  Thank you!  If
that's not acceptable, then I would suggest we add a Usage Note to the F&O that
says "BTW, there are special considerations in using Regex's with collations. 
Please take a look at UTS18 if you are planning to do that."

It was decided on the joint WG telcon on June 7, 2005 to close this comment by
adding a note to the F&O section 7.6.1 that says "It is recommended that
implementers consult [Unicode Regular Expressions] for information on using
regular expression processing on Unicode characters."

The working group agrees to your changes. We thank you very much and
