Re: [xsl] double document merge using keys

[Michael Kay <mike@xxxxxxxxxxxx>]

By default, if you compare two untyped attributes using gt with an XSLT 
2.0 processor, it compares them as strings, not as numbers. You should 
either make your processing schema-aware so it knows these attributes 
are numbers, or you should force them to be numbers by explicit casting.
