In TeX there are specific accents for math: \tilde A etc. In MathML there does not seem to be such a thing. The msup, mover etc. constructs are much less specific and much more variable: for example, some people may use ∼, others may use ˜, for the tilde accent. They seem to encode the idea that one may use any character as a superior to or over another character. For the well-known math accents that is not appropriate; one would like to use specific accent characters. Is there a specific or recommended set of characters which are suitable for accents on math variables? The symbols in the entities file isodia.ent http://www.w3.org/TR/MathML2/isodia.html may be a good candidate set. But they are all spacing accents, which by themselves are already higher and smaller than a normal character. This situation seems to be identical to the prime, discussed on this list: http://lists.w3.org/Archives/Public/www-math/2002Nov/0024.html. As an extreme example, ˙ is dot above. Using it in an munder would not seem appropriate: <mml:munder> <mml:mi>A</mml:mi> <mml:mi>˙</mml:mi> </mml:munder> In fact, it works nicely in MathPlayer and Mozilla.
