Interesting question [... that the WG should sort out for MathML 3 :> ] My first inclination would be to think of them as nesting (a box around a circle around the content, versus a circle around a box around the content), simply because it is hard to see (and harder to specify) how many of the various pairs should overlap (eg. how should "radical roundedbox" look?) OTOH, I suspect the original intention was that they would overlap (in which case the order doesn't matter), since that can create many more effects than we would want to list as explicit values. Further, nesting can easily, and more clearly, be done simply by nesting <menclose>'s. If this is the concensus of the WG, we at least should clarify this. speaking for myself, bruce -- bruce.miller@nist.gov http://math.nist.gov/~BMiller/Received on Thursday, 30 October 2008 12:39:06 UTC
