Not so sure. If legal:paragraph has a content model that requires a
header, and xhtml2:header's expect sections as their @about
container, it could be more appropriate to derive legal:paragraph
from xhtml2:section.

And marking the role on a <section> or <p> would convey the
same information to legal:namespace-aware processors; what
would vary would be the handling in XHTML2 processors that
were legal-unaware.  In which case to process as a <section>
might be the highest and best fit in pure XHTML2.

[I blather.  The problem with ontologies is that there are *so many*
ways to skin a cat.]

But if what the legal community calls a paragraph walks like an
xhtml2:section and quacks like an xhtml2:section, it is best to use
the most restrictive element type (from the more commodity
vocabulary) that fits, before extending with @role qualification.
