Section 8.4 says: 

   ...
   A media session within a conferencing system can have any number of
   floors (0 or more) that are represented by the conference identifier.
   When using SDP offer/answer exchange to negotiate a floor control
   connection with the focus using the call signaling interface, the
   unique conference identifier is contained in the 'floorid' SDP
   attribute, as defined in [RFC4583], e.g., a=floorid:1 m-stream:10 .
   Each 'floorid' attribute, representing a unique floor, has an
   'm-stream' tag containing one or more identifiers.  The identifiers
   represent individual SDP media sessions (as defined using 'm=' from
   SDP) using the SDP 'Label' attribute, as defined in [RFC4574].

It should say:

   'mstrm' tag containing one or more identifiers.  The identifiers
   represent individual SDP media sessions (as defined using 'm=' from
   SDP) using the SDP 'Label' attribute, as defined in [RFC4574].

Notes:

In section 6 of the RFC4583 the ABNF for the "floorid" attribute is: floor-id-attribute = "a=floorid:" token [" mstrm:" token *(SP token)]

The text string "mstrm" is used to reference the media stream rather than "m-stream" that appears in this section.

Section 8.4, pg.27 says: 

The 5th and the 6th paragraph on pg.27 both contain the clause:

   ...
   When using SDP offer/answer exchange to negotiate ...

It should say:

Both instances should say
either:

   ...
   When using SDP offer/answer exchanges to negotiate ...
                                       ^

Section 9.3,1st para says: 

                                           [...].  This kind of
|  operation is called "1st party signaling" and they do not affect the
   state of other participants in the conference.

                                                 ^^^^^^^

Notes:

Grammar: "they do" does not match "This kind of operation".

Section 9.6,2nd para says: 

   Figure 15 provides an example of one user "Alice" who's chairing a
   fixed length conference with "Bob" and "Carol".  The configuration is

                                     ^^^
   10 minutes left in the conference.  At that time, "Alice" is moved
   into a sidebar created by the conferencing system and only "Alice"
   receives the announcement.

Notes:

Typo distorting the proper sense of the text.
See also Figure 15 -- the warning is sent *to* "Alice".
