But these aren't unknown tags in tidy since they're html5, they're just unknown in Edbrowse.  I'm wondering if there's anything we can do in the meantime whilst
we get our html5 support completed to at least provide the html5 stuff as part of the DOM for use by js.  Any ideas?  I think that header, footer (probably
comment and fragment too) should be treated like div in edbrowse, and probably same for article (and it's subtags) but obviously js needs to see the original
element types.  From memory there are a few more div-like tags as well though I can't remember what they are without going through the spec.
<video> is for embedding video files and, I think, <canvas> is some sort of drawing element though I don't know what it does (or if it can be used) with text.

Cheers,
Adam.
