 Form construction
 ------------------

+some generic building blocks which will greatly help you in building forms
+properly integrated with |cubicweb| (coherent display, error handling, etc...)

-XXX feed me
-:Vocabulary control on relations:
+A form basically only hold a set of fields, and is bound to a renderer that is
+responsible to layout them. Each field is bound to a widget that will be used
+to fill in value(s) for that field.
+

+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+.. autoclass: cubicweb.web.formfields.Field

-    editing views, it returns a list of couples (label, eid) of entities
-    that could be related to the entity by the relation `rtype`
-  * `subject_relation_vocabulary(rtype, limit=None)`, called internally
-    by  `vocabulary` in the case of a subject relation
-  * `object_relation_vocabulary(rtype, limit=None)`, called internally
-    by  `vocabulary` in the case of an object relation
-  * `relation_vocabulary(rtype, targettype, x, limit=None)`, called
-    internally by `subject_relation_vocabulary` and `object_relation_vocabulary`
