 ## Syntactic Validation
 
-- The length of the `Tag` must not be larger than `64`.
-- The length of `Data` must not be larger than `8192`.
-- Given the type and length information, the _Tagged Data Payload_ must consume the entire byte array of the `Payload`

+- The length `Len` of the `Tag` field must satisfy: `0 <= Len <= 64`.
