[Zope] custom zclass content object

[Marko Kruijer]

I am trying to create a custom object under control_panel/products
What i want is a simple object that i can give properties that will 
automatically be indexed by a zcatalog.

I have succeeded in doing this already, however I have based my object 
on the DTML document base class.
I want to use page templates to display my content, but this only works 
if i call the template over the object like so: 
http://mysite/myobject/template

I would like the object to call the template itself, so that i don't 
have to change urls by adding the template to them.
If I create a DTML document and call the page template in the source it 
does not find the object, only it's parent. I know this is because of 
acquisition and in a page template i would solve this by calling a macro 
and in the macro calling i.e. tal:content="template/property"

I can't seem to find the equivalent in DTML for this command. Is there any?

I've also tried using other base classes for my content object but there 
are no simple ones afaik.

Does anyone have suggestions on what path to choose here?
