I know this is not a bug, konqueror does well his job, but the fact is that other browsers are more tolerent about this, so I would understant if you mark this as WONTFIX.

If a mix of old html and xml syntax is used for the last attribute before the end of the tag and if there is no space before the / khtml does not take it into account. (my english is very bad so an example will be more usefull)

This tag is true xhtml (no problem with this)
<input type="checkbox" name="test" value="test1" checked="true" /> Test1<br/>

This tag is not valid xhtml because of the attribute checked with no value,
but khtml have no problem with this.
<input type="checkbox" name="test" value="test2" checked /> Test2<br/>

This tag is not valid xhtml either but there is no space between "checked"
and /> . Khtml won't check the checkbox.
<input type="checkbox" name="test" value="test3" checked/> Test3<br/>

I know that this is because the code is bad, but forms are more important than cosmetic so perhaps that an exception could be made for that ?

Regards.
