It doesn't matter if people use an XHTML syntax. As long as these files are sent from the web server using text/html, and don't kid yourself most of them are, then they are still rendered as HTML. The true benefit of using the XHTML syntax is that you can use XML tools (that might be part of an existing tool chain) to output and manipulate your pages before they are served.
