This test check whether the standard JCR node types are exposed as defined in the
spec. Some of the checks are too strict because certain aspects of a standard node
type can be implementation variant:
- 22.214.171.124.2 "Additions to the Hierarchy": additional super types are allowed, but
the test currently fails if a standard node type has more than the specified super
- 126.96.36.199.4 "Variant Attributes": some metadata mixins defined in JSR 283 have
variant OPV settings and protected flags, but the test currently fails if an
implementation differs from the standard settings/flags.
