Re: [xsl] Need an XPath expression for: $B is not contained in $A

Doh!--how do I keep failing to understand that "=" is atomic value comparison?

Maybe I shouldn't try to solve XSLT puzzles first thing in  the morning.

Cheers,

    Comparing the string value with "=" does not compare the node identity 
    so I don't think this is a good idea, unless textual equality is sought.
