This is really great. 

Due to the global scope of a sort key and the brevity of the spec on
sort keys and the sort() function, there are still some questions:

1. Are there any limitations on exp2 above? Would it be allowed to
contain xsl:variable references, xsl:function references or the key()
function?

2. Would it be possible for exp2 to contain a reference to a locally
defined xsl:variable (not a top-level one)?
