** need a more specific name. summary is too generic sounding of an element name for this special usage. Similar to the problem with <code><address></code> (special use - for contact information for the document, but used as a generic "address" for street addresses).
** alternatively make a generic <code><summary></code> element - make it an actual summary inside <code><article></code> or <code><body></code>, as well as inside <code><details></code>. Another advantage is that this is close to the semantic of the Atom "summary" element, and the hAtom microformat 'entry-summary' property.
* <code>sandbox</code> feature on <code><iframe></code> should be considered for removal.
** needs security review
** will be a lot of work to implement
** may not actually solve the problem it is intending to solve
** get more input from Jonas Sicking
