	A 'res' element indentifies a resource. A resource is typically
	some type of asset, such as a photo, song, video, etc.
	A 'res' element contains a URI that identifies the resource.

Attributes:

'importUri'			type: anyURI			use: optional
	The 'importUri' attribute is the optional uri locator for
	resource updates.

'protocolInfo'		type: string			use: required
	The 'protocolInfo' attribute is a string that identifies the
	streaming or transport protocol for transmitting the resource.
	If not present then the content has not yet been fully imported by
	the ContentDirectory service and is not yet accessible for playback.

'size'				type: unsignedLong	use: optional
	size, in bytes, of the resource.

'duration' 			type: string			use: optional
	The 'duration' attribute identifies the duration of the playback of
	the resource, at normal speed.

The format of the duration string is:
	H+:MM:SS[.F+], or H+:MM:SS[.F0/F1]
	Where:
	+H		one or more digits to indicate elapsed hours,
	MM		exactly 2 digits to indicate minutes (00 to 59),
	SS		exactly 2 digits to indicate seconds (00 to 59),
	F+		any number of digits (including no digits) to indicate fractions of seconds,
	F0/F1	a fraction, with F0 and F1 at least one digit long,
			and F0 < F1.
	The string may be preceded by an optional + or - sign, and the
	decimal point itself may be omitted if there are no fractional	seconds digits.

'bitrate'			type: unsignedInt		use: optional
	The bitrate in bytes/second of the resource.

'sampleFrequency'	type: unsignedInt		use: optional
	The sample frequency of the resource in Hz

'bitsPerSample'	type: unsignedInt		use: optional
	The bits per sample of the resource.

'nrAudioChannels'	type: unsignedInt		use: optional
	Number of audio channels of the resource, e.g. 1 for mono,
	2 for stereo, 6 for Dolby surround, etc.

'resolution'		type: string			use: optional
	X*Y resolution of the resource (image or video).
	The string pattern is restricted to strings of the form:
	[0-9]+x[0-9]+
	(one or more digits,'x', followed by one or more digits).

'colorDepth'		type: unsignedInt		use: optional
	The color depth in bits of the resource (image or video).

'protection'		type: string			use: optional
	Some statement of the protection type of the resource
	(not standardized).

The equivalent MPEG21 DIDL element is 'RESOURCE'.
