/*
 * These functions validate whether a string corresponds to a Guatemalan tax
 * identification number, also known as 'Numero de Identificación 
 * Tributaria' (NIT). They employ regular expressions for this purpose, utilizing
 * the metacharacter shorthand '\d' instead of '[0-9]' to save space.
 * The approach is highly optimized for bandwidth reduction; readability and
 * maintenance are not prioritized over optimization. You can observe how this
 * regular expression works through the following links:
