Comment (by davidhassell):
Hi Tim,
My motivation came from considering how the simple geometries could fit
into the CF data model (CFDM).
In the CFDM, coordinates and their bounds are bundled up into a single
construct (the "auxiliary coordinate construct" in this case). In the
usual case, matching coordinates with their bounds is unambiguous, via the
`bounds` attribute. The node coordinates are essentially bounds (albeit
complex ones) to the coordinates, so I was looking to extend the
definition of coordinate bounds to allow for these geometries. For this to
work, I was looking for a similarly robust way of pairing up coordinates
with their node coordinates (i.e. "bounds"). We can't rely on standard
names, for example, because they are optional; nor units, for example,
because they could be the same for both X and Y coordinates.
I hope that I'm making sense,
David
