It says the value is 4 octets.  That's not quite saying it's an integer, was there a later one?

I think it's arguably more useful as an integer though, for the reasons listed previously, and because 
you can use expr to build the bit string easily.

For example:

update reply {
	Egress-VLANID += "%{expr:822083584 + %{Tagged-VID}}"
}

With hex you need to manually pad the VID out to 12 bits.
