XHTML, as practiced
Tim Berners Lee: The attempt to get the world to switch to XML, including quotes around attribute values and slashes in empty tags and namespaces all at once didn’t work.
Nor, apparently, did the attempt to get people to separate attribute names and attribute values with an equal sign as Firefox, IE, and Opera all display this blog entry just fine. (Can somebody test this for me in Safari?)
This common behavior isn’t reflected in the WHATWG draft.
I am growing increasingly of the belief that one of the ramifications of driving towards “Radical Simplification” is that one must plan for, and accommodate, those that use simple text editors and templates.
