Re: [calsify] I-D Action: draft-ietf-calext-ical-relations-06.txt

[Michael Douglass <[e-mail]>]

I do have a follow up related to Murray Kucherawy's comments on case 
sensitivity for the eventpub draft:

For linkrelparam we have this:

linkrelparam = "REL" "="
                ("SOURCE"      ; Link to source of this component
                / DQUOTE uri DQUOTE
                / iana-token)   ; Other IANA registered type

First the abnf is wrong - it should be "LINKREL" not "REL"

The values (other than the uri) should case-insensitive strings from the 
link relations registry in rfc 8288

Given that shouldn't the abnf be something like:

linkrelparam = "LINKREL" "=" param-value

with a paragraph specifying that a value can be "source" along with a 
description.

param-value is defined in 5545:

      param-value   = paramtext / quoted-string

      paramtext     = *SAFE-CHAR

The quoted string MAY be a URI representing an extension relation type 
as defined in rfc8288 section 2.1.2

I guess iana-token can look the same but it's semantics are different

      iana-token    = 1*(ALPHA / DIGIT / "-")
      ; iCalendar identifier registered with IANA

The value will be registered with IANA (we hope) but it won't be an 
iCalendar identifier.
