I have an AF element and I want to reference a child element's attribute in an Analysis function. I know I have seen this done, but do not remember how (or which documentation it was in...). Example:
I have element "P" with child "C". I want to create an add-hoc analysis for P that performs calculations on attribute C.a, C.b, etc. and stores them in element P.x.
I do not want to use a template, as P is already based on an existing template, and this is a one-off.
