DM>strict conformance (*all* products in a class must be functionally DM>the same) [was a policy] that may...apply... DM>only to some classes of product. MS>As far as applying to only some classes of products, I don't believe MS>this is true. Strict conformance clearly applies to all classes of MS>products. 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. .................David Marston
