Doh! Please pay no attention to me ... I completely misread your question :-(
I read the bit inside quotes as "Python_external_method". Bad me! No cookie!

Onto the real answer: 
 
My understanding is that the namespaces are inherited for dtml-methods, so if
you replace my gibberish above with

	<dtml-var the_other_dtml_method>

you should still be able to talk about sequence-item. In a recent Zope site I
have been working on, I did a lot of things that were exactly like this. The
only difference was that because, in my case, sequence-item was a tuple, I
would have things like this:

	<dtml-with "my_method_that_returns_a_list_of_tuples()">
		<dtml-let name="_['sequence-item'][0]"
		          title="_['sequence-item'][1]">
		<dtml-var display_data>
		</dtml-let>
	</dtml-with>

In this example, display_data was a dtml-method that put the 'name' and
'title' things in a table and it just referred to them as <dtml-var name> and
<dtml-var title>. So talking about <dtml-var sequence-item> should be the
same.

My sincere apologies for the entirely misleading answer earlier.

Cheers,
Malcolm
