But it's goint to move away from the riginal HTML a XML goals and trength: human readable a writable code.
Who can see if all tags are properly cosed and what the burrow is, when it's not perfectly formatted and indented?
Indention is still up to the author in XHTML 2. Of course, now you must indent <section> elements and all content within to create a meaningful structure. This is more a move directed at automation of blogging software/ CMSes and the like. I also don't indent every <div> on my page, all I need to do is validate... and check the template closely.
