I don't agree. Escaping doesn't mean "adding a prefix", it means "switching
to a different encoding convention", or "breaking away from the constraints
imposed by the current rules". I find the usage "< is escaped as <"
perfectly natural (once the strangeness of the transitive verb wears off).
But naturalness, of course, is a matter of opinion.
