define different document modes for different ie version using meta tag

Hello guys!

Our application uses html5 doctlype.

We are trying to make ie7-ie9 work with IE7 standard mode and IE10 and IE11 with their own standard modes.

I've found an article on msdn explaining how to do that using meta tag.

According to it I tried to use this meta tag in our application:

< meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7,10,11" >

However it did not work properly. IE9 was still using IE9 standard mode.

I also tried to use "IE=EmulateIE7, IE=IE10, IE=IE11","IE=EmulateIE7; IE=IE10; IE=IE11","IE=EmulateIE7, IE=10, IE=11" however it did not work properly.

Did I make a mistake? Is there any other way to force ie work in desired document mode?

Thanks a lot!
