all looks great. Purposes and Natures look fine to me (there is no "one 
right answer")

Not directly. In the original/current RDDL i.e. http://www.rddl.org/ you 
can nest <rddl:resource> elements as they themselves contain %Flow.mix, 
but in the new RDDL proposal it looks like that (marginal) feature will 
get lost.

Basically RDDL natures are rdfs:Class'es and RDDL purposes are 
rdf:Property's.
