Section 5.3. says:

5.3.  Session Name ("s=")

      s=<session name>

   The "s=" field is the textual session name.  There MUST be one and
   only one "s=" field per session description.  The "s=" field MUST NOT
   be empty and SHOULD contain ISO 10646 characters (but see also the
   "a=charset" attribute).  If a session has no meaningful name, the
   value "s= " SHOULD be used (i.e., a single space as the session
   name).

It should say:

5.3.  Session Name ("s=")

      s=<session name>

   The "s=" field is the textual session name.  There MUST be one and
   only one "s=" field per session description.  The "s=" field MUST NOT
   be empty and SHOULD contain ISO 10646 characters (but see also the
   "a=charset" attribute).  If a session has no meaningful name, the
   value "s=-" SHOULD be used (i.e., a single dash as the session
   name).

Notes:

In 3rd paragraph of section 5. is written: whitespace MUST NOT be used on either side of the "=" sign, which is incosistent with subsection 5.3. Therefore I suggest to use "-" (single dash) instead of " " (single space) for sessions without meaningful name.
