Do you really need the HEAD tags, or can you just place the META tag at the
end?  And do you need it within the HTML tag?  I can see a quick fix just to
append the META tag to the end of your HTML, without bothering with the HEAD
or placing within the closing HTML tag.

This particular anomaly bears repeating its best solution.....
