An obvious design principle is that the chosen delimiter should not need to
be escaped when entered on the command line of common shells (including,
eek, COMMAND.COM)

Off the top of my head (I'm really not sure about it) this leaves only "-"
and "_".

It's probably irrelevant to note (but that's never stopped me in the past)
that "-" as a delimiter in names is the convention for XSLT itself.
