Sure, you just call absolute_url on the object, or, you can use the
var tag option to do that, or, you can use the URL entity reference.

For example, suppose you want to provide a URL to 'X', which
may come from a variety of places.  You can use any of:

  <dtml-var expr="X.absolute_url()">

or 

  <dtml-var X url>

or

  &dtml.url-x;

All of these are equivalent, and the last is probably the best, 
since it is short and is handly when used in a tag attribute, as
in:

  <a href="&dtml.url-x;">See X</a>
