Where in OSI RM is SSL situated?

Hi there,

sorry for being slightly off-topic (since this is not a Linux-specific
question,) but I'm not quite sure where to situate SSL in the OSI reference

If I had to decide I would put it as the lowest sub-layer into the session

Here's why: TCP sockets are the service access points of the transport layer,
right? SSL sockets generalize regular TCP sockets, right? So they should be
situated above TCP sockets? They provide certain QoS and sessions, so SSL
should be in the session layer, shouldn't it?

Thanks for your insights,
