Confusion between transferId and Request ID in BTP error codes?

[michielbdejong]

There are two error codes that refer to transferId of packets/requests but in the specification but it seems what is meant is Request ID?

Also in this context it would make sense to rename error F03 from TransferNotFound to RequestNotFound

Other error codes refer to fulfillment, such as:

The transfer cannot be fulfilled because it has already been rejected or expired.

Even though BTP transfers don't seem to have a condition.

Do the transferId and conditions in these error codes refer to ILP-level transfers?
