That would avoid the problem that attributes named xmlns:* are
represented differently in the DOM in text/html and application/xhtml
+xml.
However, it still has the problems:
1) prefix-based indirection confuses people and, therefore, causes
bugs (as seen with Namespaces in XML)
2) the indirection is not robust under copying and pasting.
3) looking up URLs wastes time when people need to write the URLs in
markup or in software that processes markup
4) using URIs as identifiers makes the language verbose

To avoid violating our DOM Consistency design principle, the DOM-wise
same mechanism would need to be used in XHTML5 as well.
