Hi everybody.

I'm currently looking at what it takes to clean up the current draft 
(see 
<http://greenbytes.de/tech/webdav/draft-reschke-webdav-search-latest.htm>) 
so that it can be submitted to the RFC Editor for publication as 
Experimental RFC -- it seems to me that would be the right step, there's 
clearly not sufficient energy to fully complete the work, but there are 
lots of implementations out there that would benefit from a stable spec.

Anyway, one of the issues we probably can't avoid fixing is the issue of 
string comparisons, that is collation sequences.

In this case, two very similar approaches come to mind:

(1) Rely on XSLT collations 
(<http://www.w3.org/TR/xquery-operators/#collations>), requiring support 
for codepoint-by-codepoint 
(<http://www.w3.org/2005/xpath-functions/collation/codepoint>), or

(2) Rely on 
<http://www.ietf.org/internet-drafts/draft-newman-i18n-comparator-14.txt>.

Both give us roughly the same features, however (2) has the severe 
drawback that it only defines the collation registry, but not an actual 
collation we could require (we need at least a basic one that works for 
non-ASCII characters).

Feedback appreciated,

Julian
