Re: lack of identifying keywords in iCal grammar

1. Yes, you are correct in pointing out that the "duration" token was used in the ABNF for two different purpose. This has been corrected. "dur-value" used for duration values and "duration" used for DURATION property.

2. The current ABNF for ianaparam, xparam, etc. is correct. These are mechanisms for either registering new parameters (ie, ianaparam) or extending the specification with non-standard properties parameters. 
3. The iana-token is a token in the iCalendar ABNF to specify more generic parts of the iCalendar grammar. For example, how a property is composed of a name; which is a IANA registered token. This allows us to describe a concept like properties in generic terms. The actual iana-token is a registered component type, property name, parameter name, enumerated value, etc.
