I received this good question during the IESG review of geo location module:

> * Is WGS-84 still the default for geodetic-datum when astronomical-body != "earth"?
> ...
> I don't know enough YANG to know if the "when" statement is usable in this case to constrain the applicability of this default or not.

Is there a way to specify a conditional default in YANG?

A separate but related issue I ran into the other day is that I have a Boolean in a grouping that can default to true or false (in the actual software) depending on where it is included... Also curious if that's solvable.

Thanks,
Chris.
