It probably ended up that way. I think it's pretty close as it stands 
but not explicit. I'll add some text to specify how iCalendar parameters 
map on to link header attributes - if there is a mapping - e.g. LABEL 
<-> title and that specifications that wish to use LINK types with 
attributes specify how to map paramaters

I've not done an exhaustive search through but at the very least 
privacy-policy and terms-of-service would satisfy a need that was 
expressed some time ago for published events. copyright, edit, 
edit-form, license, payment all look useful.

And all the interval... link types look more properly like calendaring 
relations
