Section 5.6 says:

   date-time       = full-date "T" full-time


      NOTE: ISO 8601 defines date and time separated by "T".
      Applications using this syntax may choose, for the sake of
      readability, to specify a full-date and full-time separated by
      (say) a space character.


This specification seems ambiguous; the ABNF allows only “T”/“t” as the separator, but the “NOTE:” paragraph describes acceptability of other separators.

It’s unclear what “this syntax” refers to: if “this” refers to ISO 8601, then it seems irrelevant, but if “this” means RFC 3339, then the paragraph conflicts with the ABNF.

I’m not sure of the proper fix because I don’t know the intended meaning.
