9/// A [`SignedTransactionIntentV2`] is an inner model for a [`NotarizedTransactionV2`].
10///
11/// It includes two parts:
12/// * The [`TransactionIntentV2`] which contains a representention of an intent tree
13/// with a root transaction intent, and other subintent descendents. These subintents are
14/// flattened into an array in the model.
15/// * It also includes intent signatures, some for this transaction intent, and separately,
16/// an array of signatures for each each flattened subintents.
17///
18/// ## Similar models
19///
20/// A [`SignedPartialTransactionV2`] is a similar structure for a fully signed partial subtree
21/// of a transaction, but with a subintent root. Whilst useful for constructing a
22/// transaction, it doesn't appear under a [`NotarizedTransactionV2`] because the subintents
23/// get flattened.
