Q:

Customized Node Display for 'Document Template' Content-Type

I want to filter the nodes of content-type Document Template.  I know this can be done with .tpl.php files. 
I was wondering, what was the right file name convention.  I tried the the naming convention but it does not work. 
node--document template.tpl.php

Where did I go wrong?

You used the wrong format.  Replace the space with a -:
node--document-template.tpl.php
