RFC 2251 does not say the root DSE contains subschema attributes.
RFC 2251 says that the root DSE, as well as all objects, should
have a subschemaSubentry attribute whose value refers to the
controlling subschema entry (or subentry).
I note that one should whenever possible ready the subschemaSubentry
from the object they wish to modify (or from its parent if adding
a new entry) as different entries may be controlled by different
I also note that LDAPv3 schema discovery, in particular the semantics
of the subschemaSubentry attribute of the Root DSE, will likely
be updated by the IETF as the defined mechanism is known to be
flawed in numerous ways [see IETF LDAPext and LDAPbis WG mailing lists

No. It should return all non-operational attributes of the root DSE.
Please see the archives for further details on how to read the
controlling subschema of an object.
