Jonathon, Thanks for the "Welcome". It looks like this book is a really good match for my level of semi-expertise. My point is you can have the simplicity of the HTML5 doctype and not use any of the advanced features. I'm doing that on any new websites I develop. That way I'm ready if it is appropriate to add an HTML5 feature some time in the future. I've already used the CSS3 feature "border-radius" which shows up nicely on recent browsers and causes no problems with any old browsers.

Here's a quote from HTML5 The Missing Manual. "When Will HTML5 Be Ready? The short answer is “now.” Even the despised Internet Explorer 6, which is 10 years old and chock-full of website-breaking quirks, can display HTML5 documents. That’s because the HTML5 standard was intentionally created in a way that embraces and extends traditional HTML." I can see there was no point in adding complication to the 4th Edition however the HTML5 doctype is ready to use for all the code in this book. Doing so would simplify some of the "boiler-plate" code without the need to use any of the HTML5 advanced features. Perhaps that will be appropriate for the 5th Edition.
