Ken,
I re-reviewed the questionable statement in MIPv6-13 and I think your point
was right. And now I think that sentence was quite perplexingly tricky,-
because there are two subjects for a predicate verb 'process' in one
sentence. The first half part in the sentence is saying the node's IPv6
encap/decap module processing, while the latter is saying the node's
transport layer processing - trickily with two commas.
Sooo amusing! :>
Big thanks,
Jiwoong
