I don't understand the problem.  The comments relationship doesn't say 
it's about comments, it says contains comments.  The definitions for 
comments and feed are:

     Designates a resource containing user contributed comments...
     Designates a resource used as a syndication format.

With comments and feed, it should indicate a "resource used as a 
syndication format containing user contributed comments".  Perhaps the 
sentence you cited above could be clarified to reflect this better.

I somewhat agree with this, although it seems that it is just the 
definition of alternate that is poorly worded.  If it were defined more 
like this, alternate stylesheet would be more appropriate:

   Designates substitute versions for the document in which the link
   occurs or, when used in conjuntion with another link type, an
   alternate version of the resource type indicated.

(that definition is not perfect, but I think you'll understand what its 
supposed to mean anyway)

I somewhat disagree that bookmark does this.  It's defined as:

   "...A bookmark is a link to a key entry point within an extended

Unless I'm mistaken, a permanet link for the document doesn't really 
seem to fit that defintion.
