If that is your intent, that is what you should use, not some cryptic 
notation <>. An interface is either a valid Fortran interface, meaning 
it parses through a compiler and the standard explains what it means 
(like a valid C prototype), or it is something else, which to me makes 
no sense unless you do what you suggested: You give a valid interface 
and then you say "an implementation may use other mechanisms but the 
intent/semantics must be obeyed as if this interface were used"...in 
which case you better be clear about what the intent/semantics is.

No, there is no officially published way to do this yet. This is why 
some of us suggested it is premature to publish the revised interface.
