    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.

    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 preceeding the identifier; label is linked to a Wikipedia article (in this order):
    redirect from id_handlers['<id>'].redirect when use_identifier_redirects is true
    Wikidata-supplied article name for the local wiki from id_handlers['<id>'].q
    local article name from id_handlers['<id>'].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')

    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.

    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 preceeding the identifier; label is linked to a Wikipedia article (in this order):
    		redirect from id_handlers['<id>'].redirect when use_identifier_redirects is true
    		Wikidata-supplied article name for the local wiki from id_handlers['<id>'].q
    		local article name from id_handlers['<id>'].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
