I added a tutorial on how to create a legend to annotate/filter based on the complex query for flows of a generalized type of a flow element. This is related to the earlier post on connectors and flows. This has a different query as it navigates from the association to the flow, to the conveyed item, and then to the generalized type. The query then looks in the collection of generalized types for a matching type. For example, we could have management data and project data with a lot of different messages in each category. Using the base type in the legend, we can annotate and hide/show according to the base type.
