Evaluates the content of last/surname (authors etc.) parameters for multiple names.
Multiple names are indicated if there is more than one comma or any "unescaped"
semicolons. Escaped semicolons are ones used as part of selected HTML entities.
If the condition is met, the function adds the multiple name maintenance category.

Same test for first except that commas should not appear in given names (MOS:JR says
that the generational suffix does not take a separator character). Titles, degrees,
postnominals, affiliations, all normally comma separated don't belong in a citation.

<name> – name parameter value
<list_name> – AuthorList, EditorList, etc
<limit> – number of allowed commas; 1 (default) for surnames; 0 for given names


Evaluates the content of author and editor (surnames only) parameters for multiple names. Multiple names are

Compares values assigned to various parameters according to the string provided as <item> in the function call.
<item> can have on of two values:
'generic_names' – for name-holding parameters: |last=, |first=, |editor-last=, etc
'generic_titles' – for |title=

There are two types of generic tests. 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 be
rejected so the 'accept' test prevents that from happening. Accept tests are always performed before reject
tests.

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). The intent of all this complexity is to make these searches as fast as possible so
that we don't run out of processing time on very large articles.

Returns
true when a reject test finds the pattern or string
false when an accept test finds the pattern or string
nil else

cs1|2 shares some parameter names with xml/html atributes: class=, title=, etc. To prevent false positives xml/html

tags are removed before the search.


If a missing pipe is detected, this function adds the missing pipe maintenance category.

Look at the contents of a parameter. If the content has a string of characters and digits followed by an equal
sign, compare the alphanumeric string to the list of cs1|2 parameters. If found, then the string is possibly a
parameter that is missing its pipe. There are two tests made:
{{cite ... |title=Title access-date=2025-08-05}} -- the first parameter has a value and whitespace separates that value from the missing pipe parameter name
{{cite ... |title=access-date=2025-08-05}} -- the first parameter has no value (whitespace after the first = is trimmed by MediaWiki)
cs1|2 shares some parameter names with XML/HTML attributes: class=, title=, etc. To prevent false positives XML/HTML
tags are removed before the search.

If a missing pipe is detected, this function adds the missing pipe maintenance category.
