Hello, First of all, I realize that the MathML extension is a work in progress, and thus, the current design may be different than what I'm looking at (the mathml example that comes with the fop 0.92 beta).

That said, I'm concerned that the approach used by this extension is going to have some problems. In the current scheme, MathML is converted to SVG by jeuclid, and the resulting SVG is then laid out like any other graphic. Ignoring, for the moment, the fact that JEuclid seems to give incorrect bounds for some equations, there is also another problem: the text baseline. The solution of converting to SVG and treating it like an image works OK for block-display equations, but for inline-display equations it does not. Consider a simple mathematical expression 'i_0' ('i' with a '0' subscript). The i's baseline should be consistent with the text around it, while the zero's baseline should be slightly below the main text baseline. But this scheme for integrating fop/jeuclid would instead put the zero's baseline consistent with the surrounding text. Perhaps you're already aware of this, but as a fop user who would like to see robust equation support, I thought it worth pointing out.
