That won't fly in a standard; implementors will baulk because they are 
being asked to do something which may be impossible on some systems.

There is, however, something called "normative encouragement".

So you can say something like:

"Type thread_id must meet the requirements given here, but is otherwise 
implementation defined. Implementations are encouraged to give thread_id 
the same type and values as in the underlying native thread system, if 
possible."
