... The difference between a published XML schema and a PDV is subtle. On the one hand, even if not mandatory, a PDV may discard useless nodes in the XML schema, by removing sub-trees or by replacing a path between two nodes by a single “//” edge. Removing nodes helps improving schema management, storag ...
