Overview of Typical SPDL Document
The SPDL document defines several collaboration aspects of the shared place.
The header defines the communication protocol used for contact with collaboration server. (could be CORBA or what have you)
Next, all the shared objects embedded in the shared place are enumerated.
The following fragments define the user groups that have access to the shared place, specific user roles, and types of the collaborative sessions that are established in the shared place.
Other fragments describe how the data visible by different users are synchronized and specify the sources of the content presented by the shared objects.
Note how some Shared Place properties (e.g. users and files) are useful in non-collaborative page mode and others support both synchronous and asynchronous collaboration
