Detects but ignores nowiki and math stripmarkers.  Also detects other named stripmarkers

See also coins_cleanup().
 
Output of this function is an error message that identifies the character or the

for multi-byte characters, the position of its first byte) in the parameter value.

Gets name list from the input arguments


Searches through args in sequential order to find |lastn= and |firstn= parameters (or their aliases), and their matching link and mask parameters.
Compares values assigned to various parameters according to the string provided as <item> in the function call.
Stops searching when both |lastn= and |firstn= are not found in args after two sequential attempts: found |last1=, |last2=, and |last3= but doesn't
<item> can have on of two values:
find |last4= and |last5= then the search is done.
'generic_names' – for name-holding parameters: |last=, |first=, |editor-last=, etc
'generic_titles' – for |title=


This function emits an error message when there is a |firstn= without a matching |lastn=When there are 'holes' in the list of last names, |last1= and |last3=
There are two types of generic testsThe 'accept' tests look for a pattern that should not be rejected by the
are present but |last2= is missing, an error message is emitted. |lastn= is not required to have a matching |firstn=.
'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.


When an author or editor parameter contains some form of 'et al.', the 'et al.' is stripped from the parameter and a flag (etal) returned
Each of the 'accept' and 'reject' sequence tables hold tables for en.wiki (['en']) and local.wiki (['local'])
that will cause list_people() to add the static 'et al.' text from Module:Citation/CS1/en/ConfigurationThis keeps 'et al.' out of the
that each can hold a test sequence table  The sequence table holds, at index [1], a test pattern, and, at index
template's metadata.  When this occurs, the page is added to a maintenance category.
[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.

archive.org saves a snapshot of the target page in the url.  That is something that Wikipedia should not allow

The old form does not support or map to the new form when it contains a display flag.  There are four identified flags
In this function, vxxxxors = vauthors or veditors; xxxxors = authors as appropriate.
('id_', 'js_', 'cs_', 'im_') but since archive.org ignores others following the same form (two letters and an underscore)

This function is used to validate a parameter's assigned value for those parameters that have only a limited number
of allowable values (yes, y, true, live, dead, etc.).  When the parameter value has not been assigned a value (missing
or empty in the source template) the function returns the value specified by ret_val.  If the parameter value is one
of the list of allowed values returns the translated value; else, emits an error message and returns the value
specified by ret_val.

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=2016-03-17}} -- the first parameter has a value and whitespace separates that value from the missing pipe parameter name
{{cite ... |title=access-date=2016-03-17}} -- 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.
