I shouldn't have used the term “errata” there because it is a term-of-art for nontechnical grammatical/spelling errors and the minor like.  I should have utilized ‘technical defect’ or some such term instead, because technical defects go in a corrigendum whereas purely-linguistic errors go in errata.  The ambiguity of UTC vis a vis offsets therefrom in past editions of the ISO/IEC Ada standard are a defect in the meaning, not a mere linguistic-/syntactic-oops erratum.
