Re: unrecognized actiontype in maction

Yet another comment again :-)

For statusline and tooltip, the second child is a <mtext> in general but 
can be non-<mtext> too (maybe converted into text).
Displaying an arbitrary non-<mtext> message or doing the conversion are 
not necessarily easy things. What about doing something like <semantics> 
i.e. allowing fallback messages in the next children. For example

<maction actiontype="tooltip">
<mrow>...</mrow>
<msqrt><mn>2</mn></msqrt>
<mtext>Square root of 2</mtext>
</maction>
