the association graph for a bean is often a tree with secondary beans 
being properties from a primary bean. the elements in xml (ignoring 
ID/IDREFs) also form a tree. a very common use case is when the element 
-> bean transformation is an isomorphism. in other words, when there is 
a one-to-one correspondence between elements and beans.

i think maybe an example would help (some properties suppressed):



and this kind of thing:


i think that craig's point is that CallMethodRule is aimed at this very 
common use case and that it'd be better to add another rule that 
performs another function for other use cases. this has the advantage 
of reducing the complexity of the code and also makes it easier for the 
user to find the functionality they require.

(hopefully he'll jump in about now if i've misrepresented his opinions
