The 'accept' tests look for a pattern that should not be rejected by the'reject' test.  For example,|author=[[John Smith (author)|Smith, John]]would be rejected by the 'author' reject test.  But piped wikilinks with 'author' disambiguation should not berejected so the 'accept' test prevents that from happening.  Accept tests are always performed before rejecttests.Each of the 'accept' and 'reject' sequence tables hold tables for en.wiki (['en']) and local.wiki (['local'])that each can hold a test sequence table  The sequence table holds, at index [1], a test pattern, and, at index[2], a boolean control value.  The control value tells string.find() or mw.ustring.find() to do plain-text search (true)or a pattern search (false).
