/**
 * Utility to require one of two optional properties,
 * e.g. $value OR value must exist, but not both.
 *
 * Explanation, we pass in '$value' | 'value':
 * 1. R extends keyof T = keyof T  ->   means that what is passed in (R) must be/extend keys of first arg (T)
 *
 * 2. Omit<T, R> means what we pass in (R) is omitted from T
 *
 * 3. 2nd part of the union simplifies to   ->   { [K in keyof Required<T>]... }['$value'|'value']
 *
 * 4. which then simplifies to  ->  { $value: ...; value: ...; }['$value'|'value']
 *
 * 5. which then simplifies to  ->  {
 *      $value: Required<{ '$value'?: string }> & { 'value'?: undefined };
 *      value: Required<{ 'value'?: string }> & { '$value'?: undefined };
 *    }['$value'|'value']
 *
 * 6. which then simplifies to  ->  {
 *      $value: { $value: string };
 *      value: { value: string };
 *    }['$value'|'value']
 *
 * 6. and finally  ->  { $value: string } | { value: string }
