Priority: Urgent

Released In: 2.0.0
Target Release: major

Last Change By: GeorgeClark
Currently the htmldoctype setting in the foswiki.tmpl and the foswiki.pattern.tmpl is set to

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "">
<html xmlns="" xml:lang="%LANG%" lang="%LANG%">

Should be

<!DOCTYPE html><html lang="%LANG%">

Confirmed. This is a minimum requirement to switch modern IEs into standard mode. Otherwise it will fall back to IE7 "Almost Standards" mode ... which isn't really supported anymore. See also

In addition this one-liner should go into the html head as well:

<meta http-equiv="X-UA-Compatible" content="IE=edge">

Even better would be to add an X-UA-Compatibility http header to the communication. Listing it in the html head is not 100% reliable as it might fall off the radar of IE reading the first bites while downloading the html document. Better would be to flag IEs as early as possible to give its best rendering html.

The most recent checkin has broken the HTMLValidationTests.

Specifically, the <meta charset="%CHARSET%" /> setting upsets the tests; and one of the templates has a missing quote.

Michael, I'm rewinding the effect of this checkin until you have a chance to review.

No,don't revert. I have filed another task about these validation failures. See Item13134.
