OK, I think that I am perhaps misusing zclasses then.  Here is what I

I have a Folder that was created by using the 'Add new item' menu
within Zope.  This folder is called 'Site'.

I have a Zclass called 'theatre_class' that has "Base classes ZObject,
_ZClass_for_CatalogAware, _ZClass_for_DTMLDocument".  I have set the
zclass to have the following properties by creating a
'theatre_class_property' property sheet for it:
... amongst others.

Within the Folder 'Site', I have standard_html_header dtml-method that
is an edited version of the default one that is found in the root
folder of a Zope instance (if that is the right term).  This
standard_html_header uses things code such as this:
<title><dtml-var head_title></title>
<META NAME="description" CONTENT="<dtml-var meta_description>">
<META NAME="author" CONTENT="<dtml-var meta_author>">

When I use the standard_html_header in an instance of a zclass, the
appropriate property of the zclass is indeed inserted into it.  See

Zclass instance has code such as:

<dtml-var standard_html_header>

<h1>This is an instance of my Theatre Zclass</h1>

<dtml-var standard_html_footer>

However, if I try to put <dtml-var id> into the standard_html_header,
I get nothing, and if I use <dtml-var document_id>, I get
'standard_html_header' inserted into the document.

I hope I have made it clear what I am doing.  It is certainly becoming
clear to me that I have got the wrong end of the stick a little with

Thanks for your help.
