Good question.

Apparently my memory didn't serve me correct information, as I thought
that GRDDL transformations were first identifiers for a set of
"rules", second a possible implementation of those rules, usually in
XSLT. However, it seems that they are now expected to actually work
for any client, so using just an identifier apparently isn't good

Fair enough, but my concern was that we'd be open to accidental grddl'ing...

The simplest thing that could possibly work...

Perhaps we should take this to another forum, perhaps even try to
write a note or something along those lines.
