clean XML answer is not available, i.e. (simplified)

So it is not possible to embed RSS 2.0 in OPML or vice-versa.
In both specifications, the correct thing to do is to point at the other
relevant file, in OPML with an "rss" nodetype and in RSS either with the
<link> element of <item> or your own custom namespace, depending on
the application. In general, if an HTML rendering of the OPML file
exists I would point <link> at that and have a custom namespace of your
own for pointing at the OPML file.
If you are willing to control the readers which are consuming your RSS,
you *could* define your own namespace like
"http://cdeaandrss.blogspot.com/almost-opml-in-rss", and declare that
the tags inside of that namespace are *just like* the ones in the
official OPML spec... but that would be a derivative specification, and
you should not call that OPML as no current OPML reader is likely to be
able to read it. The most standards-compliant thing to do is probably
just to provide a link to the relevant OPML file, which current OPML
consumers will be able to read.
