You don't need a dictionary for the pointing to work: a minimal index of
lemmas used in the project would be enough.
The mechanism is a kind of feature structure. The main reason for
preferring it over anything else is that it reduces the information to
atomic form: no matter how many instances of a given "word" you have,
you don't have to worry about variation creeping into to your
lemmatisation if you define the lemmas in one place and point to them
from the instances (of course you can get the pointers wrong, but that
is easily checkable). We use a similar structure in the header all the
time to list things we will be pointing to elsewhere in the document.
This wouldn't go in the header, but the principles are the same: keep
the data in a single place, and avoid markup on the atts.
In something huge like Dante, I can see the lemma list to be an
extremely useful tool. You are probably building one anyway--one assumes
you aren't composing the lemmas on the spot for each word--so this is a
way of just using the work.
