+// On reading a RecordedTransaction, an unrecognized chunk is skipped using
+// the size information in the ChunkDescriptor. Chunks are read and either
+// assimilated or skipped until an End Chunk is encountered. This has three
+// notable implications:
+//
+// 1. Older and newer implementations should be able to read one another's
+//    Transactions, though there will be loss of information.
+// 2. With the exception of the End Chunk, Chunks can appear in any
+//    order and even repeat, though this is not recommended.
+// 3. If any Chunk is repeated, old values will be overwritten by versions
+//    encountered later in the file.
+//
+// No effort is made to ensure the expected chunks are present. A single
+// End Chunk may therefore produce a empty, meaningless RecordedTransaction.
