BIP16 P2SH defines special rules to apply on scripts with a specific pattern, namely:
OP_HASH160 <scriptHash> OP_EQUAL.
My question is: Can a P2SH be used within a script? So can I e.g. make a scriptPubKey:
<420000> OP_CHECKLOCKTIMEVERIFY OP_DROP OP_HASH160 <scriptHash> OP_EQUAL?
Or must all additional opcodes be in the redeemScript so that the whole scriptPubKey follows the pattern mentioned in the BIP16 above?
