===Unique Identification===
PSBTv2s can be uniquely identified by constructing an unsigned transaction given the information provided in the PSBT and computing the transaction ID of that transaction.
PSBTv2s can be uniquely identified by constructing an unsigned transaction given the information provided in the PSBT, and computing the transaction ID of that transaction.
Since PSBT_IN_SEQUENCE can be changed by Updaters and Combiners, the sequence number in this unsigned transaction must be set to 0 (not final, nor the sequence in PSBT_IN_SEQUENCE).
The lock time in this unsigned transaction must be computed as described previously.

When an output is added, it must have PSBT_OUT_VALUE and PSBT_OUT_OUTPUT_SCRIPT set.

If the input has a required time based timelock, then PSBT_IN_REQUIRED_TIME_TIMELOCK must be set.
If the input has a required height based timelock, then PSBT_IN_REQUIRED_HEIGHT_TIMELOCK must be set.
If an input has both types of timelocks, then both may be set.
In some cases, an input that can allow both types, but a particular branch supporting only one type of timelock will be taken, then the type of timelock that will be used can be the only one set.
