Originally this was an empty element, contained in <Rule>. That is, for each <Rule> there was one <Condition>. A way to order the rules, so that different conditions were applied in a pre-determined sequence, was needed, so the order attribute to <Rule> was added. Later on <Condition> became a true container, and there was no indication that a <Rule> could not contain more than one <Condition> or that a <Condition> could not contain another <Condition>. It seems to me that the first method had the advantage of simplicity and modularity (in that you could actually copy and paste rules from one document to another without having to worry too much about unintended consequences). However, there was no way to express hierarchies or sequence of actions other than through the "order" element. The second method, while allowing the direct expression of hierarchies through document hierarchy, has the distinct disadvantage of presenting obstacles to simple copy and paste. I'm not convinced, however, that this is a practical disadvantage (as opposed to theoretical). But if we are to retain this second method, then we have to re-examine the need for the "apply" attribute as well as "order". > ---------------------------------------------------------------- > To subscribe or unsubscribe from this elist use the subscription > manager: <http://lists.oasis-open.org/ob/adm.pl> -- Eduardo Gutentag | e-mail: eduardo.gutentag@Sun.COM XML Technology Center | Phone: (510) 986-3651 x73651 Sun Microsystems Inc. |
