I am working on some older software, some of which was written for IE-5 quirks mode. We currently use meta tags to display the code in IE-5 quirks compatibility mode. I am trying to assess the feasibility of refactoring it to a stricter compliance with existing standards.
It will make this job much easier if I can obtain a list of deprecated/nonstandard features present in IE-5 quirks mode. If there is a "IE-5 quirks to HTML 5 strict" dictionary I would consider naming my firstborn after whoever can find it (in lieu of a bounty).
The closest answers I have been able to find are:
difference-between-quirks-mode-and-standards-mode-javascript. Which unfortunately appears to be limited to IE-9 quirks
How to force Internet Explorer to view a page in compatability mode (or not) which appears to take more of a scatter-gun approach (I am looking for something a little more comprehensive).
