Ambiguous Unsupported Limit

In the Table 48. "Required Limits" Unsupported Limit column, it mostly seems to me that it lists the exact value the limit member should have when the feature is unsupported.

But the text strongly implies the limit is either `min` or `max` type.

E.g. for `maxViewports` value `1` it is ambiguous whether if the feature is unsupported the value "must be 1" or the value "must be greater or equal to 1".

Furthermore some Unsupported Limit values seem to be missing (`-`). E.g. `primitiveOverestimationSize`, and I am unsure what that means (can be any value??).

Furthermore in the Limit Type column authors write random stuff, but the footnote says it should only be min or max.
