[whatwg] text/html conformance checkers and optional tag inference

[Henri Sivonen]

Does any What WG document specify what optional tag inference features 
a conformance checker for the text/html flavor is required to implement 
and what elements are required to be considered empty?

Should What WG require tags that were optional in HTML 4 to be 
mandatory?
