Because human beings write computer programs: 1. It is necessary to perform three tests rather than one to identify a name from XHTML: that means three separate patterns in XSL (for example), three separate contexts in a context-sensitive search engine, three separate XML queries, three separate XPointers, etc. etc. All of this means three times the opportunity for bugs and interoperability problems (and yet more accusations that the W3C cannot create specs that work together). 2. If the intention of XHTML is to continue to create new Namespaces for future versions of XHTML, you run into a serious deployment problem where old software will not work properly with new documents. If you don't believe that versioning is a problem on the Web, then look at the lack of even Java 1.1 applets for general use (because Netscape 3.0 doesn't have a Java 1.1 VM).
