Why? ... both are good ... I think apply-templates + sort is not 
as readable as for-each + sort ...

PS. The question is actually very reasonable. The XPath paper  
is mixing 2 notations for no reason - plain inconsistency... I'll vote 
for regexpr form, btw ... after years of recursion-based yacc, 
I'm now enjoying regexpr-based metamata ... I think regexpr-based 
is easier to understand... Why you think it is evil ?
