Missing schema name for base collation of a collation?

[Mark Rotteveel]

Shouldn't RDB$COLLATIONS also have a RDB$BASE_COLLATION_SCHEMA (or
RDB$BASE_COLLATION_SCHEMA_NAME) column?

Given the syntax of CREATE COLLATION allows you to specify either
existing collation (which has a schema) *or* an external name, I would
expect the schema to be stored.

Am I missing something, or is this an oversight?
