Target denied
The target attribute of a tags is no longer allowed in HTML (HTML 4.01 Strict and XHTML 1.0 Strict).
This is technically corect since HTML is for marking structure of a document and opening things in different windows is a user-interface issue and hence is within the domain of javascript.
What's really odd though is the suggested workaround. Mark tags that need to open in a different frame or window somehow (rel="external" for instance) and then use a javascript function to give all those links a target attribute.
Seems silly to me.
