Though it would be lovely to come up with some equivalent of Linnaean taxonomy (Kingdom, Phylum, Class, Order, Family, Genus, Species) when it comes to the various magico-religious streams, I do not think that it is practical. Physical living things have relatively distinct boundaries whereas systems of culture that are passed from and through individuals and communities through non-genetic means have a high degree of form complexity and overlap. Moreover the overlapping domains of the magico-religious streams are not limited to nesting hierarchies of set and subset. Also, the Traditions of the magico-religious streams are anchored in more than just the physical plane and the rules of the other planes also apply.
