I had noticed the double pink dot, but was not sure yet if it was a bug or served some specific purpose. I'm alternating between reading the FAQ/examples and trying things from an intuitive UI experience. So apologies for the noise. Being a programmer myself I know that doing the hallway test is a good way to see if a piece of software works intuitively.

I see that you are using the one argument in an mrow idea from http://www.w3.org/TR/MathML2/chapter3.html#id.3.3.1.2 -- ok, that makes sense.

You probably didn't notice the second pink dot within the fences. Place your x' there. See

for more details

Yes, the prime is located rather high.

So a standard type of expression in formulae I am working with is something like:

g(x, x')

This I would, in presentation MathML, write as:

[code]
<mi>g</mi>
<mfenced open="(" closed=")">
<mi>x</mi>
<msup>
<mi>x</mi>
<mo>&prime;</mo>
</msup>
</mfenced>
[/code]

FireMath adds an extra <mrow> within the <mfenced>, which causes the separator to not be added. Which is logical for it will now treat the entire <mrow> as one argument within the <mfenced>.

[code]
<mi>g</mi>
<mfenced open="(" closed=")">
<mrow>
<mi>x</mi>
<msup>
<mi>x</mi>
<mo>&prime;</mo>
</msup>
</mrow>
</mfenced>
[/code]

So at the moment I am stripping these myself from the resulting MathML.

Also, is it just me, or does the prime (with StixFonts) seem to hover awfully high above the identifier within Firefox?
