[Zope] Conditional sections

[Dale Strickland-Clark]

Hi list.

I've been chewing this over for a while and my solutions seem unduly 
complicated. I wonder if I'm overlooking something simple.

I have a page template which contains a macro. This template is used by itself 
and also called from other pages which invoke the macro.

When called as a macro, I want two images included which I don't want when it 
is called alone.

Here's an extract: 

<img tal:replace="structure here/images/q66" tal:condition="includeimage" />
<div metal:define-slot="body">
Some default content...
</div>
<img tal:replace="structure here/images/q99" tal:condition="includeimage" />

What I /think/ I need is some code I can put before the <tal:macro-define...> 
that sets some variable I can test in this tal:condition. 

Alternatively, is there some other test I can make to see if this is running 
inside a macro or not?

Thanks.
