The Future is XHTML 2.0
An anonymous reader writes "As with its past, the future of HTML will be varied, some might say messy, but I believe XHTML 2.0 will ultimately receive widespread acceptance and adoption. A big move in this direction will be in Embedded devices such as phones and digital TVs, which will have no need to support the Web's legacy of messy HTML, and are free to take unburdened advantage of XHTML 2.0. This Developer Works article examines the work of the World Wide Web Consortium (W3C) in creating the next-generation version of their XHTML specification, and also their response to the demand for 'rich client" behavior exemplified by Ajax applications.'
Bad examples, for your point. Stage Coaches, horse drawn carriages, and Model T's can operate on current roads. They just have to follow current rules. You'll actually see horse drawn carriages fairly frequently in some areas. They'd get a ticket on the freeways, but so would a car that has their top speed.
Also: Television signals still are in a format black and white TV's accept. They can't read the whole signal, but they work just as well as they did before.
This is how the web's evolving. The current standards are built on past ones, and older browsers can usually use most of a newer site. Same as horse drawn carriages and black and white TV's.
'Sensible' is a curse word.
Just wanted to point this out:
XHTML2 -- with navigation lists, links on any element, sections and headings -- is optimized for web documents.
HTML5, officially Web Applications 1.0 -- with canvas, a drag and drop API, and XMLHTTPRequest standardization -- is optimized for web applications.
CSS3 is going to be extremely cool.
