Yes, this would be a Good Thing in terms of current and likely
future multilingual use. It is often convenient to give IDs
a semantically meaningful name, in the appropriate language.
This means that a linkName should allow either entity names or
non-ascii position characters (or both), neither of which are
possible if linkNames are NAMEs.
