Or are you suggesting that we should provide such a reference as a kind of historical note explaining how we arrived at our specification? Michael Kay (personal response) 3082 2 ashok.malhotra 2005-05-25 21:57:18 +0000 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." Ashok Malhotra (personal response) 2718 3 ashok.malhotra 2005-06-07 16:46:29 +0000 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." 4334 4 fsasaki 2005-06-22 09:01:05 +0000 consenus of the i18n-core-wg (telecon 21 May 2005): The working group agrees to your changes. We thank you very much and regard the bug as closed. Regards, Felix Sasaki
