When IE8 goes out of beta it will act more or less according to the web standards, so they say.
But it's possible to make it act like IE7 by using version targeting.
So the question is, if Dynamicweb should include the meta tag to make IE8 act like IE7 on all existing solutions, to prevent a lot of fuckup's on old websites
Of course you will be able to disable the output from the control panel.
