   8   * If there are more elements in the collection, like most jQuery get/read methods,
   9   * this method will use the first element in the collection.
  10   *
  11   * In IE6, the `attributes` map of a node includes *all* allowed attributes
  12   * for an element (including those not set). Those will have values like
  13   * `undefined`, `null`, `0`, `false`, `""` or `"inherit"`.
  14   *
  15   * However there may be attributes genuinely set to one of those values, and there
  16   * is no way to distinguish between attributes set to that and those not set and
  17   * it being the default. If you need them, set `all` to `true`. They are filtered out
  18   * by default.
