I don't think I've ever head of such a thing... escaping ampersands in tag attributes. I mean, I see what you mean about view-source highlighting them as invalid, but I've never written them that way (unless using an XML-based generation tool), nor seen any framework (JSF, etc) that ever renders them that way...
