Subject: AW: [xsl] Sorting Upper-Case first. Microsoft bug? From: Markus Abt <abt@xxxxxxxx> Date: Tue, 5 Aug 2003 21:12:58 +0200 |
David, the XSLT spec. states in chapter 10 "Sorting": [...] data-type specifies the data type of the strings; the following values are allowed: * text specifies that the sort keys should be sorted lexicographically in the culturally correct manner for the language specified by lang [...] It seems to me that the XSLT specification wants lexicographic ordering in the culturally correct manner. Mabye this is a contradiction, in this case I would regard this an error in the XSLT spec. I guess, the reference to the UTR 10 in one of the following notes in the spec. shall relate to the whole chapter 10, however, the bad HTML formatting may make one think that it only relates to case-order.

I wrote Of course XSLT 1.0 doesn't actualy define "lexicographic" but my understanding is that it always implies a direct extension on an ordering on characters to an ordering on strings by comparing the first different position. See for example the definition given here: http://mathworld.wolfram.com/LexicographicOrder.html Note that (despite the etymology) "lexicographic order" doesn't necessarily mean "the order used in a dictionary" as dictionaries are compiled by human compilers and words can appear in whatever order the compiler chooses which may reflect personal and culturalpreferences as much as logic. However lexicographic ordering is used in a technical sense as a method of extending the ordering on one set (the alphabet) to a derived set (strings over that alphabet).
