Does anyone know where to get the spec doc of CORBA object transaction server v1.2?

Why I'm asking is because there is tck case failures related to it. Glassfish v3 used in TCK env seems cannot handle the transaction service context that Geronimo sends out via corba calls. But the glassfish v2 can handle that G 3.0 sends out. Before opening a jira or tck challenge, I want to learn more details about transaction interoperability.

Appreciate any comments on this topic.
