[probably superfluous]

Every WG struggles with this trade-off between keeping it simple and 
providing the needed support. If we would agree that there is sound 
technical or pragmatic reason to be able to specify a graph-container 
type (but we are not there yet)  we have basically three options:

   1.  standardize it in a normative spec
   2.  suggest an (informative) best practice
   3.  do nothing

If the need for such a typing mechanism arises from many use cases there 
is certainly a case to be made for the first or second option. The 
decision might also depend on the overall landscape of proposed changes. 
But again, we're not at that stage yet.
