Subject:	[sca-c-cpp] NEW ISSUE:  Policy and Assembly have removed operation element from Service and Reference

---

Target:  C++ and C C&I Specification 

Description:  The Assembly TC has, in reaction to a decision in the
Policy TC, removed the operation element from Service and Reference.  The
primary impact of this is that there is no mechanism in SCDL to attach
an intent to an operation unless it is done so in the interface document
itself.  (PolicySets can still be attached to operations via an external
attachment mechanism - in the policySet definition itself).  The current
C++ and C specs allow intents to be attached, via annotations to individual
(member) functions and data members/variables.  Further, the formal
definitions of the intents defined by the Policy spec indicate that they
constrain bindings or implementations. 

Proposal: 

We have two options 

1)  Add a requires attribute to function and callbackFunction and
remove the ability for intent and policySets annotations to apply to data
members/variables 

2) Only allow intent annotations to apply to classes/sets of functions
defining an interface & sets of functions defining an implementation
and remove the ability for policySets annotations to apply to data members/variables.

My preference is option 1 (but only slightly).
