Comment:

 Replying to [ticket:13426 AGMS]:

then pkgman will fail, saying "nothing provides app:A>=1.0 needed by
 B-..." though version 2.53 is >= 1.0.  For that matter, A can do anything
 from 1.1 on up to 2.53, surely one of those versions in that range (like
 1.42 to pick one possible one) satisfies B's app:A >= 1.0 requirement?

 No. When A declares "compatible >= 1.1" it explicitly says that it doesn't
 provide (full) compatibility with earlier versions. When B declares that
 it requires "A >= 1.0", it says that it needs the functionality provided
 by version 1.0 -- which A 2.53 does not fully support.
