ABNF as2-partial-time accept time-secfrac without time-second

Please Indicate One:

• Feedback
• Blocking Issue
• Non-Blocking Issue

Please Describe the Issue:

for ABNF in Date and Time :

as2-partial-time = time-hour ":" time-minute [":" time-second] [time-secfrac]

shouldn't it be

as2-partial-time = time-hour ":" time-minute [":" time-second [time-secfrac] ]

since time-secfrac has few interest if time-second is not provided.

Good eye.
Though conceptually you can add a fraction of a second to a minute without first needing to add a second.

I don't think there are any inconsistencies with the way it is that would warrant a backward-incompatible change or adding to errata.

Again, though, good eye.

This seems like an error to me. I added an erratum here:

#550

We have an updated erratum that more closely matches our preferred format, including an explicit description of the problem and a candidate correction.

#652

• In Section 2.3 "Dates and Times", the definition of as2-partial-time allows specifying a time-secfrac portion even if time-second is not defined. One candidate correction for this error is to replace the ABNF definition of as2-partial-time with a structure that requires time-second for time-secfrac to be used:

as2-partial-time = time-hour ":" time-minute [":" time-second  [time-secfrac]]

With no responses, I have merged the PR for the errata, and I have added the new definition to the editor's draft of AS2 Core.
