XHTML 1.0 strict compliance of FORM objects (hidden fields)
FORM objects generate hidden fields that are not enclosed by any other block-level tags. This is not legal according to XHTML 1.0 strict, so e.g. pages with a mailform content object fail to validate. Attached is a patch to solve this problem (it just adds a <div> around the hidden fields block).

Error from w3's validator is (XHTML 1.1 strict!):
document type does not allow element "input" here; missing one of "ins", "del", "h1", "h2", "h3", "h4", "h5", "h6", "p", "div", "address", "fieldset" start-tag
In my case, the content area where this mailform is placed in is already inside a <div id="content"> so there is a surrounding block-level tag. But still, the input fields cannot "hang around" after the form tag. They must be enclosed inside a blockl-level tag, e.g. a <div>.
