* Get data for an feed-level element
*
* This method allows you to get access to ANY element/attribute that is a
* sub-element of the opening feed tag.
*
* The return value is an indexed array of elements matching the given
* namespace and tag name. Each element has `attribs`, `data` and `child`
* subkeys. For `attribs` and `child`, these contain namespace subkeys.
* `attribs` then has one level of associative name => value data (where
* `value` is a string) after the namespace. `child` has tag-indexed keys
* after the namespace, each member of which is an indexed array matching
* this same format.
*
* For example:
*
* // This is probably a bad example because we already support
* // natively, but it shows you how to parse through
* // the nodes.
* $group = $item->get_item_tags(\SimplePie\SimplePie::NAMESPACE_MEDIARSS, 'group');

* - `altclass` (string): If a file type is unsupported, the end-user will
* see the alt text (above) linked directly to the content. That link
* will have this value as its class name. Defaults to blank.
* - `audio` (string): This is an image that should be used as a
* placeholder for audio files before they're loaded (QuickTime-only).
* Can be any relative or absolute URL. Defaults to blank.
* - `bgcolor` (string): The background color for the media, if not
* already transparent. Defaults to `#ffffff`.
* - `height` (integer): The height of the embedded media. Accepts any
* numeric pixel value (such as `360`) or `auto`. Defaults to `auto`,
* and it is recommended that you use this default.
* - `loop` (boolean): Do you want the media to loop when it's done?
* Defaults to `false`.
* - `mediaplayer` (string): The location of the included
* `mediaplayer.swf` file. This allows for the playback of Flash Video
* (`.flv`) files, and is the default handler for non-Odeo MP3's.
* Defaults to blank.
* - `video` (string): This is an image that should be used as a
* placeholder for video files before they're loaded (QuickTime-only).
* Can be any relative or absolute URL. Defaults to blank.
* - `width` (integer): The width of the embedded media. Accepts any
* numeric pixel value (such as `480`) or `auto`. Defaults to `auto`,
* and it is recommended that you use this default.
* - `widescreen` (boolean): Is the enclosure widescreen or standard?
* This applies only to video enclosures, and will automatically resize
* the content appropriately. Defaults to `false`, implying 4:3 mode.
*
* Note: Non-widescreen (4:3) mode with `width` and `height` set to `auto`

* - `altclass` (string): If a file type is unsupported, the end-user will
* see the alt text (above) linked directly to the content. That link
* will have this value as its class name. Defaults to blank.
* - `audio` (string): This is an image that should be used as a
* placeholder for audio files before they're loaded (QuickTime-only).
* Can be any relative or absolute URL. Defaults to blank.
* - `bgcolor` (string): The background color for the media, if not
* already transparent. Defaults to `#ffffff`.
* - `height` (integer): The height of the embedded media. Accepts any
* numeric pixel value (such as `360`) or `auto`. Defaults to `auto`,
* and it is recommended that you use this default.
* - `loop` (boolean): Do you want the media to loop when it's done?
* Defaults to `false`.
* - `mediaplayer` (string): The location of the included
* `mediaplayer.swf` file. This allows for the playback of Flash Video
* (`.flv`) files, and is the default handler for non-Odeo MP3's.
* Defaults to blank.
* - `video` (string): This is an image that should be used as a
* placeholder for video files before they're loaded (QuickTime-only).
* Can be any relative or absolute URL. Defaults to blank.
* - `width` (integer): The width of the embedded media. Accepts any
* numeric pixel value (such as `480`) or `auto`. Defaults to `auto`,
* and it is recommended that you use this default.
* - `widescreen` (boolean): Is the enclosure widescreen or standard?
* This applies only to video enclosures, and will automatically resize
* the content appropriately. Defaults to `false`, implying 4:3 mode.
*
* Note: Non-widescreen (4:3) mode with `width` and `height` set to `auto`
* will default to 480x360 video resolution. Widescreen (16:9) mode with
