I'm curious at how Saxon does 
string comparisons for the purpose of implementing xsl:sort.

Saxon 6.5.2 uses codepoint collation by default, but allows you to
select a different collation by means of a user hook (selected via the
data-type attribute of xsl:sort, which is extensible).

Saxon 7.3.1 allows you to specify a collation in detail, using the
<saxon:collation> element; by default it uses the default Java collation
for the specified language, or failing that for the user's locale.
(That's for xsl:sort; for other functions such as compare(), it defaults
to codepoint collation if you don't specify a collation explicitly).
