So, if I understand you correctly, you have URLs like

       /foo/bar/xgm/blog/@@myview.html

where myview.html uses the template above, and you want that view to
have an absolute URL to

       /foo/bar/xgm/@@contact.html

?

No?

That would work.  <a href="../../contact.html">...</a>

Or you could use

  <a tal:attributes="href string:${context/zope:parent/@@absolute_url}/@@contact.html">kontakt</a>

The pattern is to get to the desired new context of the view you want to
link to, apply @@absolute_url to it, and then concatenate the new view
name to that string.

(It might be a nice extension to the AbsoluteURL view(s) to make them
traversable so that you could say obj/@@absolute_url/something_to_append
in a TALES expression.  But it wouldn't work when something_to_append
starts with '@@'.)
