Need string-compare()

XPath has a string-length() function.  It also has comparators, but the 
less-than operator always uses numbers only, never strings.

This means we cannot use the new Xforms 1.1 while attribute to sort data 
unless we also have a string-compare() function.

We also cannot find the proper place where new data should be inserted 
into an ordered list.

Must be all those extension libraries and XPath 2 users that have resulted 
in this not floating up in priority, but it should be part of the core 
language.

Cheers,
