Not at all -- I used the "html:p" simply as shorthand for something
like

  http://www.w3.org/Profiles/voyager-strict + p

(By the way, I'd like to note that I strongly dislike the idea of
having three separate HTML namespaces as proposed in the Voyager spec
[1]; after all, an HTML <a> is an HTML <a> is an HTML <a>, whether
you're using the loose, strict, or frameset version of HTML).

To the same extent, I think, that a Java program can expect
org.xml.sax.DocumentHandler to truly always describe the same class
(i.e. not perfectly, but close enough for jazz).


All the best,
