BPMN21 — visualization enumeration level

This Document is hard to read. The enumerations begins all with a rectangle independent from their level. Particularly if
there is a picture or a table between the enumerations.
I think it is better to use different signs for enumeration, depending on the level in the enumeration.
(rectangle filled, rectangle unfilled, circle filled, circle unfilled).

I know, this fact depends on at the OMG-Template (it concerns not only the BPMN-Document, I think). Now, it´s time to change the template.
