group framing code

Definition

special framing codes can be specified to support groups of primitives in CESR. Grouping enables pipelining. Other suitable terms for these special framing codes are group codes or count codes for short. These are suitable terms because these framing codes can be used to count characters, primitives in a group, or groups of primitives in a larger group when parsing and off-loading a stream of CESR primitives.

Composability property

One of the primary advantages of composable encoding is that we can use special framing code to support the above mentioned grouping.
