I see what you are saying, and the main point to note is how the two will
interact: both Semantically and technically.

It can be done, and I hope to prove this is the following weeks. I'll attach
the small example (again) at the end of this message [1]. It shows that a UI
medium can be Semantic, but still display well.

If you use that approach, then yes it is.
What you have to do is go overboard, and use every possible form of
Description on your homepage for Ora. Then you can convert that into any
Semantic media you want, but you can still present it as HTML. Once again,
see the example [1]

To that end, formation of documents such as [1] will be automatic: and *not*
hand written! (Even though I found it very easy). ;-)
What can we do with the example *now*?
1. Extract Semantic descriptions of the document itself, or one or more of
its nodal Semantic points (such as a paragraph description).
2. Generate other forms of XML (e.g. XHTML, WML) from it, easily because the
document is well described.
3. Use the foot section to generate an RDF description of the Further
Examples DL.
4. One day, hopefully, validate the dang thing.
5. Use the semantic descriptions to place it where it lies in the Web. (e.g.
extract: rel and rev).
6. Use it as a good example of Semantic markup, far removed from HTML.

P.S. I realise I need to write Schemas for it...
