To point from an element to an external authority record we would typically use either
@ref or @key. (They serve the same purpose, but @ref is
a URI, thus more useful when the referent is available on the web; @key is
arbitrary, thus more useful when the referent is not on the web.) But <person>,
<place>, and <org> aren’t members of att.canonical, and
thus don’t have @key and @ref.
Quote is from Sarah Fyge Egerton’s Poems on Several Occasions, Together with a Pastoral, 1703; it refers to figures in Virgil’s Eclogues.
