Jim, > whats the implication of adding an uppercase/lowercase function to > XSLT ? This is something that's covered in the F&O document with xf:upper-case() and xf:lower-case() in Sections 3.5.15 and 3.5.16 (http://www.w3.org/TR/xquery-operators/#b2b7b4b6c14c50). I wrote the following comments to the XQuery comments list about it: 3.5.15 xf:upper-case and 3.5.16 xf:lower-case. These functions will be a real boon if defined and implemented properly (I also think that xf:title-case would be useful, though it might be harder to define because of the way different languages do capitalisation). It would be good to revise the wording so that it's clear that a single character might map to several characters when the case is converted. For example, the lower-case 'ß' should map to the two upper-case characters 'SS'. The length of the resulting string might be different from the length of the initial string. Talking about case - proper case-insensitive comparisons and case-insensitive functions could be really useful. In particular for xf:compare(), xf:contains(), xf:starts-with(), xf:ends-with(), xf:substring-before(), and xf:substring-after(). Perhaps the treatment of case is what you were aiming to gather from the collations in these cases? Of course there are issues such as: xf:upper-case('heiße') => 'HEISSE' xf:lower-case('HEISSE') => 'heisse' but then case conversions are always a one-way process.
