Saxon 6.x uses the lang attribute to attempt to load a user-defined
sorting module, as described in [1]. There is no built-in support for
multiple languages, just hooks that allow you to do it yourself.

http://saxon.sourceforge.net/saxon6.5.2/extensibility.html#Implementing-
a-collating-sequence

Saxon 7.x allows you to use named collations as defined in the XPath 2.0
spec. The spec leaves the mechanism for creating collations
implementation-defined. Saxon provides a top-level saxon:collation
element that maps a collation name to the Java-defined collators and
locales; by default it uses the lang attribute on xsl:sort to load the
Java collator for the relevant locale.
