Indent problem

["Didier PH Martin" <martind@xxxxxxxxxxxxx>]

Hi,

Here is the problem: I want to display a SGML or XML document with markups
displayed with their properties and the content displayed in these markups.
Actually, The included script that does that but the problem is to indent
the markups to show the markups hierarchical relationships. Each markup is a
paragraph object. I need to set the "start-indent" property to a value that
reflect the markup position within the hierarchy. So that it would be
possible to see the markups hierarchy and their content.

Here is the dsssl code that works already but without indentation.This
script is inspired from Eliot Kimber tagview script.
