Expand BLA and interpret H1 as text.

Expand BLB, and don't expand BLB. Alternatively, print an error because
BLA is not terminated within BLB.

Error. BLB has no opening. Alternatively, interpret BLB as text.

Because perl is run after mhc, I'd either make <perl></perl> protect its
interior from mhc, thus resulting in example 3. If you make
perl-non-protecting, you expand both of them. <BLB> then has "</perl> as
%body.

same as above. Either you have one unclosed <BLA> or you get strange
results %)

> 6) <BLA <BLB>></BLB>></BLA> or <BLA <BLB>></BLB></BLA>

expand BLA with argument <BLB> and %body </BLB>>
and
expand BLA with argument <BLB> and %body </BLB>

both behave essentially the sames as (3)

Just pass "<BLB></BLA></BLB>" as parameter.

That's how i see it.

I think you examples are overly complicated and most of them should
simply fail because that's not legal input.
