2108 2005-09-09 15:08:43 +0000 R-119: Question about the value space for date 2009-04-21 19:25:00 +0000 1 1 1 Unclassified XML Schema Datatypes: XSD Part 2 1.0 only All All CLOSED FIXED P2 normal --- 1 sandygao cmsmcq www-xml-schema-comments oldest_to_newest 6025 0 sandygao 2005-09-09 15:08:43 +0000 The Datatypes spec states that the value space of date is the set of Gregorian calendar dates as defined in 5.2.1 of [ISO 8601]." It then says: "Since the lexical representation allows an optional time zone indicator...". However, there is nothing in 5.2.1 of ISO 8601 (at least not the 2000 edition) which suggests that a date can have an optional time zone indicator, or that suggests how it would be written if it were allowed. If this deviation from ISO 8601 is deliberate, which it seems to be, it should surely be flagged in Appendix D3. In fact, this seems to be the only case where Part 2 specifies a format that is definitely not allowed by ISO 8601; the other deviations are either restrictions, or things that ISO 8601 permits provided the parties agree.

Yes, it should have been included in Appendix D3." See: http://lists.w3.org/Archives/Public/www-xml-schema-comments/2002JanMar/0615.html Resolution: The WG resolved at the May f2f to instruct the editors to draft erratum to D3 noting the variance with ISO 8601. Proposed text: http://lists.w3.org/Archives/Member/w3c-xml-schema-ig/2002May/0049.html Erratum text approved at the June 6 telecon. Erratum E2-22 added.
