A text representation that describes how to derive addresses and spend policies for a set of keys.
Output descriptors specify scripts, key origin data, and derivation paths in a standard string format. They help wallets and signers agree on the same address set and spending policy.
A multisig descriptor might include multiple xpubs, a derivation path, and a policy like sortedmulti(2, ...).
