Owner beats lister, as in C#. A document owns its schema id; others may list it
as compatible beside its owner, in either registration order (batch 9 refused
any overlap, which forbade keeping v1 beside a v2 that declares v1's id; Soul
F8). A record resolves to the document owning its id, else to the one document
listing it. Several listers and no owner name no single document, and the load
is refused with SchemaConflictError naming the id, the record key and the
listers: refusing at registration would depend on whether the owner had
registered yet.
Every registration refusal is now SchemaConflictError (Soul F10): a second owner
of one schema id, a second document with one schema name, and a second
definition of one document type. Each names the new document's id and both
schema names and document types. Before, the last two raised CultCacheError.
Tests: an owner and a lister register in both orders and each reads its own
records, and a lister alone reads the owner's id; two listers register in both
orders, a record under their id is refused typed without its owner and is the
owner's with it, registered before or after them; two owners, one schema name
and one document type twice are each refused as a schema conflict.
