So what you mean is that an external method returns a string containing
DTML code that you want to render?

In that case, you would need to create another external method that
takes the string, creates a DTML object out of it and execute the object
something like: (untested):

from OFS.DocumentTemplate.DT_HTML import HTML

def execDTML(DTML, namespace=None, **kw):
	ob = HTML(DTML)
	return ob(namespace, kw=kw)

You would however not want to allow users to execute this directly from
the web, or you will open up a big security hole. I would recommend
restricting this to be executable by only a manager and use proxy roles
on any objects that call it.
