Its important to distinguish between the strictly hierarchical structure as expressed in the xml source (and the SVG g element) on the one hand, and the notion of set membership on the other hand. Set membership is expressed by the class attribute, whose value is a space separated list of set memberships. > You will have > to solve this one by manipulating your document's DOM.

Adding a rule to the runtime stylesheet that makes all elements in a particular set have a defined style is the easiest way to achieve this. -- Chris
