I have a ZClass which is based upon OFS: DTMLDocument and I would the new ZClass instances to contain some standard DTML just like that found in a newly created DTMLDocument....

e.g. <dtml-var standard_html_header> <h2><dtml-var title_or_id></h2> <p> This is the <dtml-var id> Document. </p> <dtml-var standard_html_footer>

Any tips?

If you create the ZClass, some contructor methods will be made, one of which is called add_<YourClass> where <YourClass> is the name of your ZClass. In there you can give your class any default values you want and also change properties. The code may give you some hints. hth Rik
