I suppose that the issue is with `external' annotations by Xpointer
that may break if the document structure changes. Direct annotations
in this case are appealing.

Then having `direct' annotations is possible maybe by having the
(X)HTML in RDF stored in a (XML) literal; where the annotation targets
may be identified by regular node ids (somehow like in Doug
Engelbart's Purple Numbers granular addressability style), to elude
identification by document structure.
