This cheatsheet is designed to be a quick reference to all of the elements and attributes available in the XHTML 1.1 specification. Because XHTML 1.1 is designed to be modular, it is organized into sections to mirror the XHTML abstract modules and the elements and attributes contained within each.

Also I included additional information relating to the XHTML Basic 1.1 specification, a minimal set of abstract modules used for small Web-based devices such as cell phones and PDAs.
