[jdev] are JIDs case sensitive?

The part you quoted is actually the part that specifies that the node is
not case sensitive. Saying that the "nodeprep profile of [STRINGPREP]"
applies to nodes (or usernames) is basically a fancy and more accurate
way of stating that usernames are not case sensitive (it also specifies
other rules). However, resources *are* case sensitive.

So:

matt at jivesoftware.com == Matt at jivesoftware.com

And:

matt at jivesoftware.com/HOME != matt at jivesoftware.com/home

It shouldn't really matter. The server should always "do the right
thing". However, using lower case always might help to clue in the user
that nodes are not case sensitive?
