 the input `relation` argument directly stored here `wp-includes/class-wp-
 date-query.php:625`

 {{{#!php
 $relation = $query['relation'];
 }}}

 and this is used on here `wp-includes/class-wp-date-query.php:667`

 {{{#!php
 $sql['where'] = '( ' . "\n  " . $indent . implode( ' ' . "\n  " . $indent
 . $relation . ' ' . "\n  " . $indent, $sql_chunks['where'] ) . "\n" .
 $indent . ')';
 }}}

 so the input arguments should be sanitized otherwise it may abuse.
