- VINCOLI DI VALIDITA' NON ESPRIMIBILI NEL DTD:
-  Siano V una variabile e T,T' due fatti/definizioni/teoremi/lemmi/corollari
-
-   - per visualizzare T dipendente da T' dove T' e T sono definiti nella stessa
-     (da definirsi) teoria/sezione, debbo visualizzare anche T'? 
-   - per visualizzare T dipendente da T' dove anche T' e' visualizzato, debbo
-     visualizzare T necessariamente dopo T'?
-   + consistenza fra la dipendenza dei lemmi e dei corollari dal loro target
-     e quella effettiva data dal livello degli oggetti
-   + tutte le URI debbono essere relative e discendenti (= non contenti "..")
-   +? ogni lemma deve precedere (strettamente?) il suo target
-   +? ogni corollario deve seguire (strettamente?) il suo target
-   + se T/V dipende da V, allora V deve essere visualizzata 
-   + se T/V dipende da V, allora V deve essere visualizzata prima di T
-    PROBLEMA: NON ABBIAMO INFORMAZIONI SULLA DIPENDENZA DI V DA V!!!
