Hi There,
I recently noticed that our RAP-based application, plus all the demo
applications I had a look at all use the following DOCTYPE:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
This DOCTYPE triggers quirks mode rendering in browsers.
Additionally, I've noticed that if you set the X-UA-Compatible header (or
meta tag) to IE=8 IE8 will render a document using IE8 Standards Mode
regardless of the DOCTYPE.
I'm wondering:
* Are there any plans to change the DOCTYPE used by RAP applications or to
allow users to specify a DOCTYPE of their own choice?
* Do you have plans for dealing with IE8 and the X-UA-Compatible header?
Regards,
Walter

Hi Walter,
I don't remember the reasons to choose this DOCTYPE. Maybe we did not
consider all options. At any rate, the DOCTYPE has to work with all
supported browsers as the same HTML code is delivered to all of them, so
changing it would require thorough testing.
If you think there are good reasons to change it, please open a bug in
bugzilla. This way, your points won't get lost.
Regards, Ralf

Based on that document:
Good news is, qooxdoo (0.8 as well as 0.7.x) supports both Quirks and
IE7 standard mode
so it is possible to run qooxdoo 0.8 in a mode that triggers a standards
rendering mode by setting
X-UA-Compatible: IE=7
obviously this doesn't take advantage of new standards support in IE 8,
but it's probable that a later version of qooxdoo will support IE 8 or
possible that the final release of IE 8 works with qooxdoo when IE 8
standards mode rendering is used.
