* The transaction input is a '''segregated witness spend''' (i.e., the scriptPubKey contains a witness program as defined in [https://github.com/bitcoin/bips/blob/master/bip-0141.mediawiki BIP141]).
* It is a '''taproot spend''' as defined in bip-taproot (i.e., the witness version is 1, the witness program is 32 bytes, and it is not P2SH wrapped).
* It is a '''script path spend''' as defined in bip-taproot (i.e., after removing the optional annex from the witness stack, two or more stack elements remain).
* The leaf version is 0 (i.e. the first byte of the last witness element after removing the optional annex is ''0xc0'' or ''0xc1''), marking it as a '''tapscript spend'''.
* The leaf version is ''0xc0'' (i.e. the first byte of the last witness element after removing the optional annex is ''0xc0'' or ''0xc1''), marking it as a '''tapscript spend'''.
Validation of such inputs must be equivalent to performing the following steps in the specified order.
# If the input is invalid due to BIP141 or bip-taproot, fail.
