I'm personally not willing to write text for this option, as I feel that it
makes the 2-byte registry ambiguous in terms of interpretation. What I
have drafted is text that refers to the inclusion of the 2-Byte registry's
contents in the low (0:0 - 0:65,535) number block of the the 4-Byte registry
by reference. If you have alternate text as clear IANA instructions that
preserves the appropriate distinction between the 2-Byte and 4-Byte AS
number registries while co-existing in a single protocol parameter
register then a request for your text that achieves this would be
appropriate.
