Olivier,
If you want to combine XForms and SMS,
https://github.com/nyaruka/rapidsms-xforms is a good place to start.
Nyaruka has done a lot of this work, and so you should make sure you
aren't re-inventing the wheel. Vumi also has some ODK hooks at
https://github.com/hodgestar/vodka, but I have no idea if that code
works.
If you want to use the XForm to encode your entire application (not
clear this is a good idea, BTW), you can put the data you want to use
(reminders, scheduling) to the XForm instance and have your
application pull the data from there. As long as you don't put those
data elements in the body, those prompts are effectively hidden from
the user (at least in the ODK/JavaRosa world)
<data id="my_xform">
<when_to_call_person>2006-09-12</when_to_call_person>
<number_of_times_to_repeat_call>3</number_of_times_to_repeat_call/>
<question1/>
</data>
<input ref="question1">
<label>What is your name?</label>
</input>
As far as feedback and non-questions, XForms can make prompts relevant
based on previous answers. So if someone says they are male, the form
can make hide (or make non-relevant) the prompts about pregnancy. You
can also have read-only prompts that are informational, or use the
hint option that each prompt has. Read
opendatakit.org/help/form-design/ to find out more.
