 the value assigned to |CitationClass= is different from the canonical template name.  |CitationClass= values are
 used as class attributes in the &lt;cite&gt; tag that encloses the citation so these names may not contain spaces while
 the canonical template name may.  These names are used in warning_msg_e and warning_msg_m to create links to the
 template's documentation when an article is displayed in preview mode.

 This table of tables lists local language date names and fallback English date names.
 The code in Date_validation will look first in the local table for valid date names.
 If date names are not found in the local table, the code will look in the English table.
 
 Because citations can be copied to the local wiki from en.wiki, the English is
 required when the date-name translation function date_name_xlate() is used.
 
 In these tables, season numbering is defined by
 Extended Date/Time Format (EDTF) Specification (https://www.loc.gov/standards/datetime/)
 which became part of ISO 8601 in 2019.  See '§Sub-year groupings'. The standard
 defines various divisions using numbers 21-41. CS1|2 only supports generic seasons.
 EDTF does support the distinction between north and south hemisphere seasons
 but CS1|2 has no way to make that distinction.
 
 33-36 = Quarter 1, Quarter 2, Quarter 3, Quarter 4 (3 months each)
 
 The standard does not address 'named' dates so, for the purposes of CS1|2,
 Easter and Christmas are defined here as 98 and 99, which should be out of the
 ISO 8601 (EDTF) range of uses for a while.
 
 local_date_names_from_mediawiki is a boolean.  When set to:
 	true – module will fetch local month names from MediaWiki for both date_names['local']['long'] and date_names['local']['short']
 	false – module will *not* fetch local month names from MediaWiki
 
 Caveat lector:  There is no guarantee that MediaWiki will provide short month names.  At your wiki you can test
 the results of the MediaWiki fetch in the debug console with this command (the result is alpha sorted):
 	=mw.dumpObject (p.date_names['local'])
 
 While the module can fetch month names from MediaWiki, it cannot fetch the quarter, season, and named date names
 from MediaWiki.  Those must be translated manually.

 This table holds non-printing or invisible characters indexed either by name or
 by Unicode group. Values are decimal representations of UTF-8 codes.  The table
 is organized as a table of tables because the Lua pairs keyword returns table
 data in an arbitrary order.  Here, we want to process the table from top to bottom
 because the entries at the top of the table are also found in the ranges specified
 by the entries at the bottom of the table.
 
 Also here is a pattern that recognizes stripmarkers that begin and end with the
 delete characters.  The nowiki stripmarker is not an error but some others are
 because the parameter values that include them become part of the template's
 metadata before stripmarker replacement.

 Error condition table.  This table has two sections: errors at the top, maintenance
 at the bottom.  Maint 'messaging' does not have a 'message' (message=nil)
 
 The following contains a list of IDs for various error conditions defined in the
 code.  For each ID, we specify a text message to display, an error category to
 include, and whether the error message should be wrapped as a hidden comment.
 
 Anchor changes require identical changes to matching anchor in Help:CS1 errors

 The following contains a list of values for various defined identifiers.  For each
 identifier we specify a variety of information necessary to properly render the
 identifier in the citation.
 
 	parameters: a list of parameter aliases for this identifier; first in the list is the canonical form
 	link: Wikipedia article name
 	redirect: a local redirect to a local Wikipedia article name;  at en.wiki, 'ISBN (identifier)' is a redirect to 'International Standard Book Number'
 	q: Wikidata q number for the identifier
 	label: the label preceding the identifier; label is linked to a Wikipedia article (in this order):
 		redirect from id_handlers['&lt;id&gt;'].redirect when use_identifier_redirects is true
 		Wikidata-supplied article name for the local wiki from id_handlers['&lt;id&gt;'].q
 		local article name from id_handlers['&lt;id&gt;'].link
 	prefix: the first part of a URL that will be concatenated with a second part which usually contains the identifier
 	suffix: optional third part to be added after the identifier
 	encode: true if URI should be percent-encoded; otherwise false
 	COinS: identifier link or keyword for use in COinS:
 		for identifiers registered at info-uri.info use: info:.... where '...' is the appropriate identifier label 
 		for identifiers that have COinS keywords, use the keyword: rft.isbn, rft.issn, rft.eissn
 		for |asin= and |ol=, which require assembly, use the keyword: url
 		for others make a URL using the value in prefix/suffix and #label, use the keyword: pre (not checked; any text other than 'info', 'rft', or 'url' works here)
 		set to nil to leave the identifier out of the COinS
 	separator: character or text between label and the identifier in the rendered citation
 	id_limit: for those identifiers with established limits, this property holds the upper limit
 	access: use this parameter to set the access level for all instances of this identifier.
 		the value must be a valid access level for an identifier (see ['id-access'] in this file).
 	custom_access: to enable custom access level for an identifier, set this parameter
 		to the parameter that should control it (normally 'id-access')
