Ignore "annotations" namespace in sitemap?

[Bertrand Delacretaz]

We talked about this at the GT and today again on irc, the goal is to 
allow structured comments in sitemaps, for example:

<map:sitemap
        xmlns:map="http://apache.org/cocoon/sitemap/1.0";
        xmlns:note="http://apache.org/cocoon/sitemap/annotations/1.0";
>
 <note:revision date="2003-12-05" author="bd">annotations added to 
sitemap today</note:revision>

 <map:match pattern="">
     <note:comment>no filename, generate list of samples</note:comment>
     <map:generate src="foo.xml"/>
    ...
   </map:match>
etc..

The TreeProcessor would ignore everything in the annotations namespace 
(Sylvain suggests adding a filtering XMLPipe just after the parser that 
reads the sitemap file).

Suggested namespace is http://apache.org/cocoon/sitemap/annotations/1.0
