Paul Bruton commented on COEL-133:
----------------------------------

We stick with the view that the caller must be able to get back atoms (minimal mandatory requirements). Use of 'exclude' in the query might make the output not a compliant atom.
On the version question: The DE can decide return only the latest version of atoms.

> In the PQI, we ought to state what is required of a data engine that has a store of Atoms of various versions.
> Is it only ever required to return Atoms in the form they were originally submitted?
> Is it permitted that a Data Engine only returns Atoms in the latest approved form?
> The PQI says that some queries return Atoms and also says that certain fields can be omitted: In this case, the return might not be a compliant Atom (because it could be missing mandatory fields). Do we allow this?
