Merges the Criteria constraining a collection into the node that retrieves it, so a multi-valued property
states what to retrieve and which items to retrieve it for in one object. Reach for it to describe an entry that
may address a collection: the merged form leaves every constraint key optional, so the same notation serves a
single-valued property, which simply carries none.
The merge is admitted on every retrieval form, keeping one notation for every entry rather than carving out
exceptions. Where a constraint key means anything is settled by the target rather than by the notation: only a
multi-valued property is narrowed by Criteria. A constraint key reaching a target that admits none is an
error rather than a key to ignore, and processors MUST reject it, reporting the offending key: on a single-valued
property, which supplies no collection to constrain, and on a Locale, which is filtered by its own tag
ranges.
