/**
 * Rule checking that uploaded file is of the correct MIME type
 *
 * The Rule needs one configuration parameter for its work: a string with a
 * desired MIME type or array of such strings. This parameter can be passed
 * either to {@link HTML_QuickForm2_Rule::__construct() the Rule constructor}
 * as local configuration or to {@link HTML_QuickForm2_Factory::registerRule()}
 * as global one. As usual, global configuration overrides local one.
 *
 * The Rule considers missing file uploads (UPLOAD_ERR_NO_FILE) valid.
