		//		A getter and setter for storing the string content associated with the
		//		module and url arguments.
		// description:
		//		If module is a string that contains slashes, then it is interpretted as a fully
		//		resolved path (typically a result returned by require.toUrl), and url should not be
		//		provided. This is the preferred signature. If module is a string that does not
		//		contain slashes, then url must also be provided and module and url are used to
		//		call `dojo.moduleUrl()` to generate a module URL. This signature is deprecated.
		//		If value is specified, the cache value for the moduleUrl will be set to
		//		that value. Otherwise, dojo.cache will fetch the moduleUrl and store it
		//		in its internal cache and return that cached value for the URL. To clear
		//		a cache value pass null for value. Since XMLHttpRequest (XHR) is used to fetch the
		//		the URL contents, only modules on the same domain of the page can use this capability.
		//		The build system can inline the cache values though, to allow for xdomain hosting.
		// module: String||Object
		//		If a String with slashes, a fully resolved path; if a String without slashes, the
		//		module name to use for the base part of the URL, similar to module argument
		//		to `dojo.moduleUrl`. If an Object, something that has a .toString() method that
		//		generates a valid path for the cache item. For example, a dojo._Url object.
		// url: String
		//		The rest of the path to append to the path derived from the module argument. If
		//		module is an object, then this second argument should be the "value" argument instead.
		// value: String||Object?
		//		If a String, the value to use in the cache for the module/url combination.
		//		If an Object, it can have two properties: value and sanitize. The value property
		//		should be the value to use in the cache, and sanitize can be set to true or false,
		//		to indicate if XML declarations should be removed from the value and if the HTML
		//		inside a body tag in the value should be extracted as the real value. The value argument
		//		or the value property on the value argument are usually only used by the build system
		//		as it inlines cache content.
		// example:
		//		To ask dojo.cache to fetch content and store it in the cache (the dojo["cache"] style
		//		of call is used to avoid an issue with the build system erroneously trying to intern
		//		this example. To get the build system to intern your dojo.cache calls, use the
		//		"dojo.cache" style of call):
		//		| //If template.html contains "<h1>Hello</h1>" that will be
		//		| //the value for the text variable.
		//		| var text = dojo["cache"]("my.module", "template.html");
		// example:
		//		To ask dojo.cache to fetch content and store it in the cache, and sanitize the input
		//		 (the dojo["cache"] style of call is used to avoid an issue with the build system
		//		erroneously trying to intern this example. To get the build system to intern your

		//		| //text variable will contain just "<h1>Hello</h1>".
		//		| var text = dojo["cache"]("my.module", "template.html", {sanitize: true});
		// example:
		//		Same example as previous, but demonstrates how an object can be passed in as
		//		the first argument, then the value argument can then be the second argument.
		//		| //If template.html contains "<html><body><h1>Hello</h1></body></html>", the
		//		| //text variable will contain just "<h1>Hello</h1>".
