So what's the problem?
Content with a doctype of <!DOCTYPE html> or <!DOCTYPE htmlplus> is
treated correctly, and content without a doctype is handled in quirks
mode, where the UA can look for </image> and if found in a suitable
place, treat the start tag as <image>, or if not found, treat the
start tag as <img>. Any content using <image> in strict mode with
another HTML doctype is broken anyway, so it doesn't really matter
how that looks.
