298295-- I spent some time thinking about whether the VirtualDatabaseContext/Schema and DatabaseContext data constructors should be the same constructor, but that would allow relation variables to be created in a "virtual" context which would appear to defeat the isomorphisms of the contexts. 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.

67−-- The @tag@ type variable can be used to specify options for converting the

70−-- > data Example = Example

80−-- result to camelCase. So @"exampleFoo"@ becomes @"foo"@ and @"exampleBar"@
