Allright, I wasn't quite aware of the Turtle/N3 semantics and made some assumptions, so I'll take a second attempt at the problem after having read up a bit. Hopefully this is more in line with the semantics.
First, the example HTML document.
<html>
<head>
<title>unification</title>
<script>alert('unified, at last')</script>
</head>
<body><p>It has to be possible!</p><p>It just <a href="imperative.html"><em>has</em></a> to be!</p></body>
</html>
Then, the Turtle interpretation
@prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> .
@prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> .
@prefix h: <urn:ns:html#> .
_:html
rdf:type h:html ;
rdf:value (
[ rdf:type h:head ;
rdf:value (
[ rdf:type h:htitle ;
rdf:value (
"unification"
)
]
[ rdf:type h:script ;
rdf:value (
"alert('unified, at last')"
)
]
) .
]
[ rdf:type h:body ;
rdf:value (
[ rdf:type h:p ;
rdf:value (
"It has to be possible!"
)
]
[ rdf:type h:p ;
rdf:value (
"It just "
[ rdf:type h:a ;
h:href "imperative.html" ;
rdf:value (
[ rdf:type h:em ;
rdf:value "has"
]
)
]
" to be!"
)
]
) .
]
) .
And the raw triples
_:html <http://www.w3.org/1999/02/22-rdf-syntax-ns#type> <urn:ns:html#html> .

Thanks to Joshua Tauberer's RDF/XML/N3 validation service.
I'm not so sure how optimal this model is, but at least it appears to me to be a feasible model. The structure being
- rdf:value for element content
- rdf:List for node ordering
- rdf:Property subproperty instances for attributes
Somehow I suspect the mechanism could be generalized for XML.
I'm not sure how easy this is to deal with (query). It's certainly verbose, but I'm not that concerned with verbosity, I'm more interested in expressiveness and how easy it is to query it - lists and such. Next step...
Comments?
Regards
Bent
