Gen-ART 33

From: Mary Barnes

Description: Section 9.5 [10.5]: While this section does have a fair amount of normative language, it is still lacking in a few cases: 
 -Item 2.:  "should" -> "SHOULD"
 -Item 5.:  "The AP sends the response…" -> "The AP MUST send the response…" 
 -1st paragraph after list: "…can directly connect…" -> "MAY directly connect"
 -2nd paragraph after list: "it can still populate" -> "it MAY still populate"
 -2nd paragraph after list: the description of the use of PING should be reworded with normative language (I'll leave that exercise to the authors)
 -3rd paragraph after the list:  "JP simply sends" -> "JP MUST send" 

Notes: Will fix text as suggested.
