SECTION 13.1.1: the sorting process

"If all the sort key values compare equal, then A will precede B in the sorted sequence if and only if A preceded B in the initial sequence." This restriction has performance consequences. Suggest adding an attribute to xsl:sort to such as stable="yes|no". XQuery has this option in ORDER BY.
