Generic CSRC List Issue

Dear All,

We have one small issue while understanding the following information from
the RTP implementation guidelines. Kind request you clarify on the last
sentence mentioned in below paragraph.
   Section RFC3095-5.7.7.6 defines the static and dynamic parts of the
   RTP header. This section indicates a 'Generic CSRC list' field in the
   dynamic chain, which has a variable length (see section RFC3095-
   5.8.6). This field is always at least one octet in size, even if the
   list is empty (as opposed to the CSRC list in the uncompressed RTP
   header, which is not present when the RTP CC field is set to 0).

If I am correct the last line "as opposed to the CSRC list in the
uncompressed RTP header, which is not present when the RTP CC field is set
to 0" , does it mean that for IR packet , one octet( first byte) of generic
scheme need not present.

Thanks
Gurushant
