Is there a mechanism to ensure that an issuer is only collecting the information defined in the schema? about protocol

Why is Faber collecting more data than the transcript? Alice wants to convince Faber of only those attributes that Faber can provide a credential for.

Alice preventing Faber to sell its data

its hard to do in practice unless Alice is sure that Faber is the only one who knows about it.

Is there anything in the sovrin foundation protocol regarding being able to trust that the date the issuer collected matches the schema definitions of the credentials they are offering

Alice and Faber can engage in a negotiation protocol where Faber can provide the reference (on the ledger) of the schema and Alice can provide only those attributes to Faber. We do not have such a negotiation documented as of now
