Re: [xsl] compare two node sets

Liam: Yes. It is the definition of "the same" that is at the heart of this 
problem (as of so many).

Cheers, Wendell

Yes. I admit i tend to avoid deep-equal for this sort of thing because of its 
behaviour with comments or processing instructions, and because the definition 
of equality tends to vary over time - e.g. wanting to ignore prefix and 
suffic/credentials elements or needing a case- insensitive comparison on family 
name to cope with latin transcriptions of Japanese family names.

But that depends on the business context - the source of the data and who 
mantains the various parts of the XSLT.
