Summary: I have no technical issues with the draft, and the text is quite easy
to understand also for someone not familiar with the topic. However, I do have
some editorial comments (specific and general) that I would like the authors to
address.

Major issues: N/A

Minor issues: N/A

Nits/editorial comments:

Q1:

Please make sure that there are references on first occurrence.

For example, the first sentence of Section 1:

"iCalendar entities often..."

...should have a reference to RFC 5545.

In addition, I don't think we use references in the Abstract

---

Q2:

The Abstract says:

"This specification updates RELATED-TO defined in..."

I think it would be good to add a few words on HOW RELATED-TO is updated.

Also, please say "RELATED-TO property".

---

Q3:

Related to Q2, in Section 9 you say that you redefining RELATED-TO. I think
redefine and update are two separate things, so please clarify.

And, while Section 1.1 does explain how RELATED-TO is updated/redefined, it
would probably be good to have some text in Section 9 too. For example, if I
understand correctly you are updating Section 3.8.4.5. of RFC 5545. That should
be mentioned.

I would also consider changing the name of Section 9 to "Updates to RFC 5545",
and then in the text describe what those updates are.

---

Q4:

The text in Section 1.1 says:

"The currently existing iCalendar [RFC5545] RELATED-TO property has no support
for..."

Please avoid "currently", because it will have a different meaning depending on
when someone reads the spec.

Instead, I suggest to simply say:

"The iCalendar [RFC5545] RELATED-TO property has no support for..."
