In this case the document is problematic, because length depends on the
particular link type, so if a receiver doesn't recognize a particular
link type, it wouldn't be able to parse the structure. (If this is by
design, you might want to be more explicit about this.)
You also need an IANA registry for link format types.

Best Regards,
Alexey
