<br><tt><font size=2> The Frame has
a structure linked to the Virtual Channel and all frames on a VC have the
secondary header (if this is used) independently they are OID or not.</font></tt>
<br><tt><font size=2>Conversely the Space Packet has a structure linked
to the APID and a mission implementing a Packet Secondary Header on Idle
Packets would just be crazy. :-) In addition, I think that, being the idle
APID fixed, there is no chance for having a Secondary header in an Idle
Packet [this is TBC].</font></tt>
