Sorry if I was being unclear. I can produce an example of what I mean
from MathML. Recall that MathML is an XML vocabulary that has a dual
purpose; formulas are written in such a way that a visual renderer
(1st Class of Product) can draw the formula with all the symbols
appropriately sized and placed, while a math interpreter (2nd CoP)
can correctly act upon the formula in math terms. The latter CoP is
broader, encompassing symbolic differentiators, a tool that plugs in
discrete values and obtains a numerical result, a tool that solves
for a different variable, etc.

It is certainly acceptable for the writers of MathML to impose strict
conformance on the first CoP, requiring that all such renderers be
able to draw the entire vocabulary, while not imposing a strict
conformance policy on products in the second CoP.
