RDF can't (or shouldn't) be embedded directly in (X)HTML - should be held separately and linked to.
In this scenario, each resource carries a tag that links it to a specific label.
Any number of resources can point to a label.
Content providers need to arrange to include the correct link to the correct label.
Or - arrange for everything to a point to a default label but to ensure that production staff then include a link to a different label that then overrides the default.
