In bes/cmdln/tests some of the tests show an odd thing. Because we eliminated hierarchy in the DAS some attributes in synthesized responses like the DDX has changed and/or gone away. This shows up in Grids. Look at these tests using COADS (a data file with Grids):
coads_climatology.ddx2.bescmd - constrained DDX
coads_climatology.ddx.bescmd - unconstrained DDX
These are currently tests 38 and 39 of ./besTest in bes/cmdln/tests.
The attributes for the Grid variables' maps are missing, but present in the copies of the Maps that appear as top-level variables in the unconstrained response. In the constrained response, only one Grid is present (and no top-level copies of the Maps). There is no attribute information for the SST Grid's Maps.
I think this is a bug, although there may be no solution we find acceptable given other constraints.
Yes, this is a bug, but not one I think we can fix easily (i.e., it will have fairly wide-ranging ramifications since changing how the DAS and DDS are combined will affect all the users of the DDX). Lets just ignore this.
