One could argue that attributes "within expressions" should be the light
ones (with only alphanumeric characters) because they are "in the way",
while attributes on items on the contrary, can be allowed to be more
visible because they apply on well-delimited and big pieces of syntax.
Also note that ocamldoc uses "non alphanumeric characters" for its
"attributes" on small (constructors) and big items.

Talking from experience, there will be a strong resistance to add a new
keyword (and it is likely that a proposal for a new keyword would use a
quite common name). So let's assume this is not an option.
