XHTML 1.1
What About it?
The latest HTML standard is XHTML 1.1. This version is based on the XHTML 1.0 Strict version with the following differences:
- All deprecated tags have now been completely removed from the standard and can no longer be used
- the lang attribute has been removed, you should use xml:lang instead
- the name attribute on the a and map tags has been removed, use id instead
- The "ruby" collection of tags has been added to the list of valid tags
These changes mean that pages coded to use this standard may use a number of tags not recognised by current browsers as well as not being able to use tags that are recognised by the browsers. As such, it is probably too early to start coding your pages using this standard yet. Maybe in another year or two.

The DOCTYPE Statement
If you do decide to code to this standard then you should code your doctype statement as described below. Remember that HTML is case sensitive so the declaration should be exactly as shown.
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN""http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
