P14: questions

[Jochen Haenisch]

Dear WG11 experts,

focus has recently been on P11e2 - maybe I can get some attention for P14
?!?

We have a couple of questions:
1) 9.10 Rule declaration:
Rules may be defined for use within a schema_view. What is the intention of
this feature? Shall these rules control the population of the view_entities
in the schema? Or shall they (also) have an impact on the referenced
original population? The latter does in our opinion not make too much sense,
but maybe there are examples that we have not thought of?!?
Similar for schema_map.

2) Reference to populations:
Is the only way of identifying populations the FROM-clause (binding extent)?
What if one wants to change a single population? Then source and target
schema are the same. In such a case it is necessary to have names for source
and target populations, not only for the schemas.
Or is this out of scope for P14?

Thanks for your attention!
Best regards, Jochen.
