didn't think of these "unnamed" arguments, now it's clear.

thanks a lot, now it's clear.
So at least, if I want to have the "old" behavior of
GettingMarkupArguments I could use the code above instead of and can use
a standard (and even better because of ""-processing) argument parsing
so when beta24 is out I will replace Cookbook.GettingMarkupArguments
with your explanations above.
