I'm asking this question after being puzzled by Joomla’s documentation here: http://ift.tt/16FVJsA

It looks as if they’re using <field> tags where I would typically use <input> tags. I searched w3.org and looked at the specs for HTML5, and can’t find any mention of a 'field' tag.

I understand that <field> is perfectly valid in an XML context, just not sure why they’re using it in place of <input> in what I would consider HTML forms.
