There appears to be a unified opinion that the developments in HTML 5 and support by browser vendors of HTML 5, make the adoption of XHTML 1.0 with hopes of the day of XHTML 2.0 a bad choice.
For this reason I have decided for my most recent project to use a strict HTML 4.01 doctype, which has required me to look back at HTML conventions such as not using greater than characters at the end of self closing tags
The question is am I doing the right thing?
