That is exactly what I ask :)

Is XQuery powerful enough to query mathmatic information which markup
by MathML Content Markup.

For example, if someone store two matrix (A - 3x5 and B- 5x4) by using
MathML Content Markup. Is XQuery power enough to produce the output a
3x4 matrics C in MathML Content Markup that  C = A x B ?

How about predicate logic, If I have two element of content E and F
E use MathML content Markup to express
{ (x) | -2 <= x <=3}
and 
F use MathML content Markup to express
{ (y) | -4 <= y <=5}
Is XQuery power enogh to perform a G = E & F 
to express a MathML content markup which express
{ (x, y) | ( -2 <= x <=3) && (-4 <= y <=5)}

?
