 /**
  *
  * Escapes an unquoted HTML attribute, or converts an array of such
  * attributes to a quoted-and-escaped attribute string.
  *
  * When converting associative array of HTML attributes to an escaped
  * attribute string, keys are attribute names, and values are attribute
  * values. A value of boolean true indicates a minimized attribute. For
  *  example, `['disabled' => 'disabled']` results in `disabled="disabled"`,
  * but `['disabled' => true]` results in `disabled`.  Values of `false` or
  * `null` will omit the attribute from output.  Array values will be
  * concatenated and space-separated before escaping.
  *
  * @param mixed $raw The attribute (or array of attributes) to escaped.
  *
  * @return string The escapted attribute string.
