Here, the design should align with `Quad`.
What's wrong with special names _for graphs_ anyway? There are 3 special
names already, and it's an extensible approach for other names - semantic
web/linked data is about naming things.
`Optional` is for a different situation, null means absent or unknown, not
"different".

> jena-text does not respect the graph setting when using the text query cache.
> In the example attached, the dataset has two graphs; the first result is
> used for the second text query. Depending on the order, either both text
> queries are zero or both one hit when the right answer is zero, once and one,
> once.
> Note also the "graph" feature of jena-text only works with quad based
> datasets (strictly, ones that use GraphView for their graphs). General
> dataset do not. This is hidden in the pattern where there is a test triple
> pattern that the literal is actually in the graph.
