===Transaction Extractor===
The Transaction Extractor must only accept a PSBT.
It checks whether all inputs have complete scriptSigs and scriptWitnesses by checking for the presence of <tt>0x05</tt> Finalized scriptSig and <tt>0x06</tt> Finalized scriptWitness typed records. If they do, the Transaction Extractor should construct complete scriptSigs and scriptWitnesses and encode them into network serialized transactions. Otherwise the Extractor must not modify the PSBT.

The Extractor should produce a fully valid, network serialized transaction if all inputs are complete.
The Transaction Extractor does not need to know how to interpret scripts in order to extract the network serialized transaction. However it may be able to in order to validate the network serialized transaction at the same time.
