Re: [xml-dev] Comparing 2 xml documents

[bob mcwhirter <bob@werken.com>]

Also, this is what XML-C14N is about.  I think xml.apache.org has new
security xml package (XML-Sig), which requires C14N functionality,
if you're working in Java.  Else, maybe there's a stand-alone
canonicalization package out there, but I'm unfamiliar.
