Are keywords such as "export" allowed as attribute names?

Here's some idea of what attributes might look like
(*DPIOO, export, exclude="f2", language="SystemC" foreign="P::Packet"*)
class packet;
extern function int f1();
extern function void f2();
endclass
class packet;
(*DPIOO, export, foreign="GetByte" *)
function byte get_byte(int j);
...
endfunction
// pragma DPI-OO export function get_byte foreign=GetByte
endclass
The benefits of attributes include clearer semantics as to which syntax elements they apply as to where they apply and that they can be interrogated by VPI.
I'd like to see attributes given more consideration given that strings can store most everything and there is no ambiguity regarding placement.

Using Syntax 22-8, the complex values supported by the proposal could be represented as strings. So that would work out OK.

Why not use/extend the `pragma directive of Syntax 22-8?

I thought the use of attributes is to be encouraged because you can't construct macros to deal with comments. Or are we giving up on attributes?
