kinds of context

Visibility and referencability really define a large part of context, context being the environment in which high-level user interactions and low-level operations occur. And there are lots of different kinds of context.

Type context is one. Operations are typically defined by type. Instance context is another--here we have instance content providing part of the operational context.

Structural context (the inverse of scope) we have already talked about--the DataSets which hold a WellKnown place a WellKnown in a larger context.

We might also extend visible and referencable rules to include explicit context, like a Python include statement. Explicit context might be defined on a type, on an instance, on a container type or container instance. The last wiki I worked on for a client had extensive explicit context but limited structural context.
