What I am wondering is if there is a simple mapping from this NoSQL
query syntax to ADQL.  My impression is that the NoSQL syntax can be
expressed as a subset of ADQL.  In that case, you are not looking so
much for extension as for a way to subset.  I already have to subset
ADQL for my services.  When I gave a talk about this at Sesto, the
consensus was to let unsupported queries fail.  So I am not sure that
anything needs to be done now.
