"at exactly 0 or more" should be "(exactly) 0 or more"?

Proposed labels: ErratumRaised, model In section 3.3.6 Rights information > table describing the Model > description of term rights: the current text is "There may be at exactly 0 or more rights statements or licenses". I wonder if it should be corrected to "There may be exactly 0 or more rights statements or licenses", thus deleting the "at" before "exactly". In addition, maybe "exactly" is not necessary in this context. All other mentions of this cardinality in the document do not contain the word "exactly" (only "0 or more"). If I am not wrong, "exactly" should be limited to cardinalities like "exactly 1", not those that allow multiple occurrences?

Thanks, @carlonim, that is indeed a valid erratum. In my view, the proper text should be (as in other similar cases in the spec):

There may be 0 or more rights statements or licenses.

Summary: Text should be changed to "There may be 0 or more…"
