Locates and returns the first set value in a table of values where the order established in the table,left-to-right (or top-to-bottom), is the order in which the values are evaluated. Returns nil if none are set.

This version replaces the original 'for _, val in pairs do' and a similar version that used ipairs. With the pairsversion the order of evaluation could not be guaranteed. With the ipairs version, a nil value would terminatethe for-loop before it reached the actual end of the list.

Adds a single Vancouver system error message to the template's output regardless of how many error actually exist.To prevent duplication, added_vanc_errs is nil until an error message is emitted.

--[=[--------------------------------------------------------------------------- Does this thing that purports to be a domain name seem to be a valid domain name? Syntax defined here: http://tools.ietf.org/html/rfc1034#section-3.5 BNF defined here: https://tools.ietf.org/html/rfc4234 Single character names are generally reserved; see https://tools.ietf.org/html/draft-ietf-dnsind-iana-dns-01#page-15; see also [[Single-letter second-level domain]]list of TLDs: https://www.iana.org/domains/root/db

RFC 952 (modified by RFC 1123) requires the first and last character of a hostname to be a letter or a digit. Betweenthe first and last characters the name may use letters, digits, and the hyphen.

Also allowed are IPv4 addresses. IPv6 not supported

domain is expected to be stripped of any path so that the last character in the last character of the TLD. tldis two or more alpha characters. Any preceding '//' (from splitting a URL with a scheme) will be strippedhere. Perhaps not necessary but retained in case it is necessary for IPv4 dot decimal.

There are several tests: the first character of the whole domain name including subdomains must be a letter or a digit internationalized domain name (ASCII characters with .xn-- ASCII Compatible Encoding (ACE) prefix xn-- in the TLD) see https://tools.ietf.org/html/rfc3490 single-letter/digit second-level domains in the .org, .cash, and .today TLDs q, x, and z SL domains in the .com TLD i and q SL domains in the .net TLD single-letter SL domains in the ccTLDs (where the ccTLD is two letters) two-character SL domains in gTLDs (where the gTLD is two or more letters) three-plus-character SL domains in gTLDs (where the gTLD is two or more letters) IPv4 dot-decimal address format; TLD not allowed

returns true if domain appears to be a proper name and TLD or IPv4 address, else false
