I don't agree, we don't do this anymore in Horde_Browser or in the  
test page for PHP versions either. It makes more sense to assume  
future versions are backward compatible and only adapt if they aren't.

So I'm +1 for adding this header.

When we first had that discussion a few years back, HTML 5 was too  
early, so we sticked with XHTML (actually we intended to convert to  
HTML 4.01 back then). I'm fine with moving to HTML 5 with Horde 5.1,  
because we don't have to change any HTML code for that. And we should  
still stick to XHTML syntax rules. I consider the syntax-laziness of  
HTML 5 a step back, and XHTML rules are compatible with HTML 5.

IMO we should be using IE=edge right now, and HTML 5 in Horde 5.1.
