Enhancement of FeatureReader

It would be nice if there was a link between initiator and schema. let say you read a folder containing XXX amount of datafiles and you are only interested in the ones that contain a specific schema. the you could read the folder, only read schema, test for the schema you want then merge that schema with the link to initiator. schema has the primary key, and initiator has the foregin key, with a 1:many relation.
