Of course this is at odds with TeX and (as indicated > above) MathML usage, which is a real drag. But then, it appears to me that (1') would be more appropriate than (1): (1') <math> <msup> <mi>X</mi> <mo>&texPrime;</mo> </msup> </math> where &texPrime; is the non-raised, non-shrunken prime symbol (TeX's \prime). Unfortunately, as far as I see, Unicode does not include it ...
