Editing Module:Authority control/config/doc (section)

=== Advanced parameters ===
* '''patterns =''' if more than one Lua pattern is needed, then use the plural form of this argument and include the comma-separated list of patterns enclosed by curly braces.
* '''prefix =''' a prefix to be included before the links. In this case numbers 1, 2, ... will be used as the labels and the '''label''' field will be ignored.
* '''valid =''' the name of a custom Lua function in [[Module:Authority control/auxiliary|/auxiliary]] used to determine if the identifier is valid or not, in case the '''pattern''' method cannot be used. It should return <code>false</code> if the identifier is invalid.
* '''customlink =''' the name of a custom Lua function in [[Module:Authority control/auxiliary|/auxiliary]] which will produce the entire external link. It should return <code>false</code> if the identifier is invalid.
* '''suppressedbyproperty =''' if this identifier should not be displayed if other identifiers are present, then specify them here in a comma-separated list enclosed by curley braces. Note: the property to be suppressed must be listed later in the list than the property which suppresses it.
* '''category =''' defines a category that should be used to track uses of this property (not usually needed). For example if <code>category = 'VIAF'</code> then [[:Category:Articles with VIAF identifiers]] and [[:Category:Articles with faulty VIAF identifiers]] will be populated.
