/// An analogue of a [`SignedTransactionIntentV2`], except with a [`SubintentV2`] at the root.
///
/// This is intended to represent a fully signed, incomplete sub-tree of the transaction,
/// and be a canonical model for building, storing and transferring this signed subtree.
///
/// It contains an unsigned [`PartialTransactionV2`], and signatures for the root subintent,
/// and each non-root subintent.
///
/// It can be prepared and validated using [`self.prepare_and_validate(validator)`][Self::prepare_and_validate],
/// just like a [`NotarizedTransactionV2`]. Its validated form is a [`ValidatedSignedPartialTransactionV2`].
///
/// It can be built with a [`PartialTransactionV2Builder`].
