No, ZCML is just for registering things, e.g. a browser page. It doesn't
really want to know what your browser page does. And a zope.formlib page
form (e.g. an EditForm) is just another browser page to ZCML.

zope.formlib will automatically adapt your object to the form interface
if it doesn't provide it. So, when you have form for IMyObject that uses
form fields from, say, IDublinCore, it will automatically adapt your
object to IDublinCore and save the modifications on the adapter.
