for example, RFC2461 7.2.4 1st paragraph does not really fit nicely
with L2 without linklayer address. the rule for attaching
target link-layer address option does not talk about cases on L2
without link-layer address.
the text is very cryptic for non-english speaker like me, i really need
a machine-readable rulesets :-)

now, we MUST attach a target link-layer address option in this case,
but how? there will be a lot more examples like this.
