/// A [`SignedTransactionIntentV2`] is an inner model for a [`NotarizedTransactionV2`].
///
/// It includes two parts:
/// * The [`TransactionIntentV2`] which contains a representention of an intent tree
///   with a root transaction intent, and other subintent descendents. These subintents are
///   flattened into an array in the model.
/// * It also includes intent signatures, some for this transaction intent, and separately,
///   an array of signatures for each each flattened subintents.
///
/// ## Similar models
///
/// A [`SignedPartialTransactionV2`] is a similar structure for a fully signed partial subtree
/// of a transaction, but with a subintent root. Whilst useful for constructing a
/// transaction, it doesn't appear under a [`NotarizedTransactionV2`] because the subintents
/// get flattened.
