Purpose
A built-in stream that starts out with one item for each public identifier built into OmniMark. These values are used by OmniMark's built-in entity manager when an entity is not resolved using the #library shelf. (This allows you to avoid having to write an external-text-entity rule.) 
An OmniMark program can add to, delete, or modify these values, as needed, with the following restrictions:
external-text-entity rules and an external reference entity is encountered.
external-data-entity or external-test-entity rule.
The default "current-item" is the last item on the shelf, as in programmer-defined shelves.
