Section: 8.4

Original Text
-------------
...
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].

Each 'floorid' attribute, representing a unique floor, has an
'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.
