Why the HTML4/HTML5 differences document should document a difference between
HTML4 and HTML5? I'm not sure how to answer that.

There was a question on StackOverflow -
http://stackoverflow.com/questions/4911085/why-does-the-w3c-validator-show-error-messages-for-these-img-attributes 

Looking at the relevant W3Schools page (
http://www.w3schools.com/html5/tag_img.asp ) which, despite it's many errors,
is still widely referred to by web authors, they had failed to pick up the
change, and state that percentages are still allowed in HTML5. 

It would seem helpful to web authors and tutorial writers alike to point the
change out in the differences document, to reduce the number of errors of this
kind.

Does that help?
