The XML Namespaces doc: http://www.w3.org/TR/REC-xml-names/ says

   An XML namespace is a collection of names, identified by a URI
   reference [RFC2396]...

RFC2396 states:

    The URI syntax is dependent upon the scheme.  In general, absolute
    URI are written as follows:

       <scheme>:<scheme-specific-part>

So I'd think that if you wanted to do this up as a proper-looking 
namespace declaration, you'd maybe just have to agree on a scheme, and 
could then use the python package name as the "scheme-specific-part". 
Perhaps something like:

    zope3:zope.app.interfaces.dublincore.IZopeDublinCore
