adjectives: predicative or attributive?

[omriabnd]

If "convenient" is treated as the main scene in "Such a convenient location, with a coffee shop around the corner", would that also be the case for:

• It's such a convenient location, with ...

• This is such a convenient location, with ...

• This restaurant is in such a convenient location, with ...

• Such a convenient restaurant, with ...

• Such a nice, convenient Chinese restaurant, with ...

• Such a convenient place to grab a sandwich, with ...

I can contribute what I understood were our conclusions from previous discussions:
In the case of 'it' and 'this':
It_A 's_S [[such_D a convenient_S (location)_A]_E location_C, [with]_E]_A
This_A is_S [[such_D a convenient_S (location)_A]_E location_C, [with]_E]_A
But without them:
Such_D a_F convenient_S [restaurant_C [with]_E]_A
Such_D a_F convenient_S [place_C [to grab a sandwich]_E, [with]_E]A
If I try to apply this logic on the example where it is nice and also convenient, I'm not sure what to do with the Relative clause:
[Such_D a_F nice_S]{H-}, [convenient_S (such)D (restaurant)_A (Relative clause missing) ]_H [[Chinese_E restaurant_C, [with]_E]A]{-H}
If the "nice and convenient" example opened with 'this' I think it should have been:
this_A is_S [a_F [nice_S (restaurant)]_E [convenient_S (restaurant)_A]_E Chinese_E restaurant_C [with]_E]

OK, so part of the challenge is the lack of an overt copula to pin the main scene on, which is why an adjective is chosen.

Ultimately I think the predication ("This is") is implicit. But I realize an implicit S may not be ideal.

In any case, it would be good for the guidelines to explain the policy so that annotators don't start using a soft notion of "emphasis" as the criterion for whether an attributive adjective should be the main scene-evoker.
