If more are needed we can reconsider, but for now it is just two.

Well, the proposals so far all seem like just as much hacks to me.
Sugestions have included only doing certain attributes, using unique
strings, appending string automatically, etc -- all are just as dodgy
IMHO, and none are actually as powerful.

Unlikely but not guarenteed impossible.

The problem is you might not only want to do it to names. You might want
to do it to certain IDs, template attributes, or even inside values or (in
certain obscure and rare but still quite fun cases) in event handler
script attributes.
