Added support so that the :paramref:`.Table.to_metadata.referred_schema_fn`
callable passed to :meth:`.Table.to_metadata` may return the value
:attr:`.BLANK_SCHEMA` to indicate that the referenced foreign key should be
- reset to None. The :attr:`RETAIN_SCHEMA` symbol may also be returned from
+ reset to None. The :attr:`.RETAIN_SCHEMA` symbol may also be returned from
this function to indicate "no change", which will behave the same as
``None`` currently does which also indicates no change.
Symbol indicating that a :class:`_schema.Table`, :class:`.Sequence`
or in some cases a :class:`_schema.ForeignKey` object, in situations
- where the object is being copied for a :meth:`.MetaData.to_metadata`
+ where the object is being copied for a :meth:`.Table.to_metadata`
operation, should retain the schema name that it already has.
