I'm not sure that the tokenized layer is something
which must be standardized, thus it's unclear that
including it in the specification would be valueable.

| Call that "abstract representation" instead.

I'd rather keep it as "transfer" representation.  
The API for this layer will be the "core" 
parser API, where the API for the serialized
format will be an extension of this interface.

Best,
