It's something like this:
<span ex:if=".age < 10">
<span>kid</span>
<span ex:if=".age < 20">
<span>teenager</span>
<span>adult</span>
</span>
</span>
The first inner element is used if the condition is true, otherwise, the
second element is used.
You can also use ex:select
<span ex:select=".doors">
<span ex:case="4">sedan</span>
<span ex:case="2">coup</span>
<span>can't be classified by number of doors</span>
</span>
You can also use "if" inside attributes:
<div ex:background-style-content="if(.sold = 'true', '#eee',
'white')">...</div>
<img ex:src-subcontent="http://foo.com/{{if(.sold = 'true', 'sold',
'for-sale')}}.png" />
