"Each should be rendered as if the others were not present" I
think addresses my question, thank you.

I think it clearly implies that the position and size of each
notation relative to child elements depend only on the child
elements (not on other notations).

I assume that implementations are permitted to position and size
the menclose (as a whole), thus positioning all the notations,
relative to the menclose's sibling and ancestor elements, in a
manner that depends on (the maximum extents of) the particular set
of notations.  But I don't think a reader would be likely to infer
otherwise from the text above.
