Re: RFC-2445: ABNF/prose mismatch on parameters

[Frank_Dawson@xxxxxxxxx]

John:
It was both through the interop testing of iCalendar/iTIP/iMIP and also an
offline comment from one of our QE folks who read the ABNF.

BTW, I sent a note to Chris Newmann, who has previously mentored the WG on
some of the iCalendar ABNF. I asked him if he had any suggestions.

One approach could be to institutionalize in a "special" ABNF occurrence
indicator, such as "&" that indicates any order to a set of elements. For
example, rather than:

     token = *(a, b, c)    ...or...  *(a / b / c)

We might specify:

     token = *(a & b & c)

With an operator that we codify within the iCalendar specification. After
all, notations do evolve.
