Allow ATTESTATIONs to attest parts of COMPOSITIONs

Description

In some situations, e.g. ICU, there can be multiple
simultaneous creators of ENTRYs in a TRANSACTION.
The ATTESTATION needs to model fine-grained attestations
of parts of TRANSACTIONs, so that the attester of
each part of the TRANSACTION is known. (Note that
the author of each ENTRY is known due to
ENTRY.information_provider).
