A quick thought about upcoming HTML5 standard.

The main advantage of HTML5 is lots of modern web features like:

• embedding multimedia content;
• 2D drawing with canvas;
• new DOM methods;
• Web Forms.

But with XHTML we still have XML comparability, that brings lots of libs and apps which can work with well formed XML/XHTML (aka parsers). So HTML5 is missing that.

HTML5 parsing will come soon after specification release, so we can start to use it believing in future.
