Hi Pete,

Yes, you have it right - the authority is RFC 2368 'mailto:' URL
(see excerpt below).

BO3-5: In the subscription object is the does the mailto URL contain '//'.
Is it <mailto://mumble> or <mailto:mumble> ?
		Proposed resolution: The mailto URL does not include '//'.

2. Syntax of a mailto URL

   Following the syntax conventions of RFC 1738 [RFC1738], a "mailto"
   URL has the form:

     mailtoURL  =  "mailto:" [ to ] [ headers ]
     to         =  #mailbox
     headers    =  "?" header *( "&" header )
     header     =  hname "=" hvalue
     hname      =  *urlc
     hvalue     =  *urlc

   "#mailbox" is as specified in RFC 822 [RFC822]. This means that it
   consists of zero or more comma-separated mail addresses, possibly
   including "phrase" and "comment" components. Note that all URL
   reserved characters in "to" must be encoded: in particular,
   parentheses, commas, and the percent sign ("%"), which commonly occur
   in the "mailbox" syntax.

   "hname" and "hvalue" are encodings of an RFC 822 header name and
   value, respectively. As with "to", all URL reserved characters must
   be encoded.

   The special hname "body" indicates that the associated hvalue is the
   body of the message. The "body" hname should contain the content for
   the first text/plain body part of the message. The mailto URL is
   primarily intended for generation of short text messages that are
   actually the content of automatic processing (such as "subscribe"
   messages for mailing lists), not general MIME bodies.

   Within mailto URLs, the characters "?", "=", "&" are reserved.

   Because the "&" (ampersand) character is reserved in HTML, any mailto
   URL which contains an ampersand must be spelled differently in HTML
   than in other contexts.  A mailto URL which appears in an HTML
   document must use "&amp;" instead of "&".

   Also note that it is legal to specify both "to" and an "hname" whose
   value is "to". That is,


     is equivalent to


     is equivalent to


   8-bit characters in mailto URLs are forbidden. MIME encoded words (as
   defined in [RFC2047]) are permitted in header values, but not for any
   part of a "body" hname.
