This design is highly assymetrical. You probably want something more like:
<evaluate op="/">
<evaluate op="*">
<variable name="winwidth"/>
<variable name="winheight"/>
</evaluate>
<number value="144"/>
</evaluate>
Then every variable is always "variable", evry number is "number"
every operator is always "evaluate", and it's the attributes to
distinguish them. That's much more XML-ish.
