Abstract
In an example implementation, a bifurcated security scheme has a first level that does not allow usage of negations and a second level that does permit usage of negations. In another example implementation, an authorization query table maps respective resource-specific operations to respective associated authorization queries. In yet another example implementation, authorization queries are permitted to have negations, but individual assertions are not.
