The purpose of this adherence is to prove that software which implements mathematically-sound design principles reaps benefits in the form of code clarity, consistency, performance, and future-proofing.

It should be possible to switch to an alternative schema to view the same equivalent information without information loss. However, allowing all contexts to reference another context while maintaining its own relation variables, new types, etc. could be interesting from a security perspective. For example, if a user creates a new relvar in a virtual context, then does it necessarily appear in all linked contexts? After deliberation, I think the relvar should appear in *all* linked contexts to retain the isomorphic properties, even when the isomorphism is for a subset of the context. This hints that the IsoMorphs should allow for "fall-through"; that is, when a relvar is not defined in the virtual context (for morphing), then the lookup should fall through to the underlying context.
