I think that is an "it is an error" case.

If you didn't expect that, what would you expect from "#ai22" or
"#aq64" or "#anoodle"?  I think those are the three types of
possibilities: unknown element size, unknown element type, or just
plain unknown.  One implementation could throw an exception; another
could widen the size to the next larger size and the element type to
generic; a third could widen all unknown tags to generic.
