That would defeat the whole point of having an XML based template engine.
I'm used to that since TAL was introduced in Zope 2, and would never go

Just assign None to readonly:
>>> print kid.Template('<span xmlns:py="http://purl.org/kid/ns#";
value="" />')
<?xml version="1.0" encoding="utf-8"?>
<span value="" />
>>> print kid.Template('<span xmlns:py="http://purl.org/kid/ns#";
value="${None}" />')
<?xml version="1.0" encoding="utf-8"?>
<span />
