Improve markup of XHTML Basic JSPX example:
- Since it is intented to be XHTML, change it to actually output XHTML instead of malformed HTML.
- Simplify by moving the DOCTYPE declaration into the file itself (Note that my understanding is that HTML5 obsoletes XHTML 1.x DOCTYPES so the DOCTYPE probably can be removed - I don't know if there is actually software that interpretes XHTML documents which are limited to an XHTML 1.1 Basic scheme).
