[Twisted-web] Radio button checked error at nevow._flat.FlattenerError

[Juanjo Conti]

I founded out that if I have <input type="radio" name="consignas"
value="1" checked /> in my HTML I get this error:
<class 'nevow._flat.FlattenerError'>:
/home/juanjo/python/twisted/teco/ter.html:21:63: not well-formed
(invalid token)

<input type="radio" name="consignas" value="1" checked="checked" />
fix it an works fine.

Greets,
