For xhtml compatibility, it would need to be 'checked="checked"'. I've
done a quick look at the html dtd, and i does look like input elements
are allowed outside of forms, but i would need to double
check... Also, the fallback to "[-]" for the partially checked state
is a bit inconsistent, perhaps changing background color or other
attributre of the checkbox would be better.

I would be willing to make this change (as an option?) to the html
exporter if others agree.
