5.5.1 Required Tests
An implementation may be tested against the core

must be processed with acceptable results for conformity assessment of
the core language. All legacy tests, as well as all modern tests for

including one or more Specialized Needs Annexes requires that all tests
for the annex(es) in question be correctly processed in addition to all

Tests that are withdrawn on the current ACATS Modification
List as maintained by the ACAA need not be processed.
