 * This requests is expected to work on semi-synchronized diagrams only.

 * By default GMF allows target editpart to decide whether the notion 
 * should be deleted from semantic model or diagram only. 
 * 
 * We are extending this behavior by allowing caller to explicitly force one 
 * or another behavior based on request property.
 * 
 * If the container for element is actually in the canonical mode, and request has Kind.NOTATION_ONLY kind, 
 * canonical mode is expected to be switched off in order to allow the expected behavior.
