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'locallong' and date_names'localshort'
	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.

These tables hold keywords for those parameters that have defined sets of acceptable keywords.
-----------------------------------------------
this is a list of keywords; each key in the list is associated with a table of
synonymous keywords possibly from different languages.
for I18N: add local-language keywords to value table; do not change the key.
For example, adding the German keyword 'ja':
	'affirmative' = {'yes', 'true', 'y', 'ja'},
Because CS1|2 templates from en.wiki articles are often copied to other local wikis,
it is recommended that the English keywords remain in these tables.

this function builds a list, keywords_xlate{}, of the keywords found in keywords{} where the values from keywords{}

this is a list of lists of valid keywords for the various parameters in key.
Generally the keys in this table are the canonical en.wiki parameter names though
some are contrived because of use in multiple differently named parameters:
'yes_true_y', 'id-access'.
The function make_keywords_list() extracts the individual keywords from the
appropriate list in keywords{}.
The lists in this table are used to validate the keyword assignment for the
parameters named in this table's keys.
