Maybe I'm missing the point, but that sounds 
an awful lot like the arguments the groves 
supporters make; the need for exhaustive defintition 
of the complete tree including all of the hidden 
values which the properties of the abstractions 
infer (eg, like the problem of the hidden 
namespace declarations when using stylesheets). 

Yes? No?

I would not use the term 'extract'. An integral step in the processing at
each node is
instantiating the particular data structure(s) which the node's specific
process
expects. This work is a necessary part of coding any executable process:
even in
those cases where the whole of the data structure required is passed in
through a well
known API, the executable code must instantiate the process instance of that
data.
