       We use MySQL to generate an ID, because it is atomic and we don't want
       to generate any conflict at zope level. The possible downfall is that
-      some IDs might be skipped because of failed transactions (MySQL is not
-      and must not be rolled back).
-      2 ZSQL methods are required for this method to work :
-       - 
-      "Length" because the id is stored in a BTrees.Length. It doesn't have
-      to be a length.
+      some IDs might be skipped because of failed transactions.
+      "Length" is because the id is stored in a python object inspired by
+      BTrees.Length. It doesn't have to be a length.
