Using MathML, inside <mrow>, I have an expression that is quite big (once rendered, the symbols occupy more space in vertical than the normal text). When I add a <mo>(<\mo> inside the same <mrow>, the parenthesis is enlarged to match the size of the expression.
For example:
<math>
<mrow>
<mo>(</mo>
<mfrac><mrow> <mn>1</mn> </mrow> <mrow> <msqrt><mrow>
<mfrac><mrow> <mi>a</mi> </mrow> <mrow> <mi>b</mi> </mrow>
</mfrac> </mrow> </msqrt> </mrow> </mfrac>
<mo>)</mo>
</mrow>
</math>
is rendered as:
Other symbols, such as "+", are not enlarged, not even if they are inside a <mo>. I would like to have brackets like "< expr >", but the following code:
<math>
<mrow>
<mo><</mo>
<mfrac><mrow> <mn>1</mn> </mrow> <mrow> <msqrt><mrow>
<mfrac><mrow> <mi>a</mi> </mrow> <mrow> <mi>b</mi> </mrow>
</mfrac> </mrow> </msqrt> </mrow> </mfrac>
<mo>></mo>
</mrow>
</math>
does not enlarge the "<" and ">":
It seems that the behavior of the various symbols is automatically selected, so that "(" is considered as a fence and "<" is not. Is it possible to override this choice, so that the "<" and ">" are resized? I tried various options of <mo> but none worked.
