	///		Text to display as a watermark when the input or textarea element has an empty value and does not
	/// 	have focus. The first time watermark() is called on an element, if this argument is empty (or not
	/// 	a String type), then the watermark will have the net effect of only changing the class name when
	/// 	the input or textarea element's value is empty and it does not have focus.
	///	</param>
	///	<param name="options" type="Object" optional="true">
	///		Provides the ability to override the default watermark options ($.watermark.options). For backward
	/// 	compatibility, if a string value is supplied, it is used as the class name that overrides the class
	/// 	name in $.watermark.options.className. Properties include:
	/// 		className: When the watermark is visible, the element will be styled using this class name.
	/// 		useNative (Boolean or Function): Specifies if native browser support for watermarks will supersede
	/// 			plugin functionality. If useNative is a function, the return value from the function will
	/// 			determine if native support is used. The function is passed one argument -- a jQuery object
	/// 			containing the element being tested as the only element in its matched set -- and the DOM
	/// 			element being tested is the object on which the function is invoked (the value of "this").
	///	</param>
	/// <remarks>
	///		The effect of changing the text and class name on an input element is called a watermark because
	///		typically light gray text is used to provide a hint as to what type of input is required. However,
	///		the appearance of the watermark can be something completely different: simply change the CSS style
	///		pertaining to the supplied class name.
	///		
	///		The first time watermark() is called on an element, the watermark text and class name are initialized,
	///		and the focus and blur events are hooked in order to control the display of the watermark.  Also, as
	/// 	of version 3.0, drag and drop events are hooked to guard against dropped text being appended to the
	/// 	watermark.  If native watermark support is provided by the browser, it is detected and used, unless
	/// 	the useNative option is set to false.
	///		
	///		Subsequently, watermark() can be called again on an element in order to change the watermark text
	///		and/or class name, and it can also be called without any arguments in order to refresh the display.
	///		
	///		For example, after changing the value of the input or textarea element programmatically, watermark()
	/// 	should be called without any arguments to refresh the display, because the change event is only
	/// 	triggered by user actions, not by programmatic changes to an input or textarea element's value.
	/// 	
	/// 	The one exception to programmatic updates is for password input elements:  you are strongly cautioned
	/// 	against changing the value of a password input element programmatically (after the page loads).
	/// 	The reason is that some fairly hairy code is required behind the scenes to make the watermarks bypass
	/// 	IE security and switch back and forth between clear text (for watermarks) and obscured text (for
	/// 	passwords).  It is *possible* to make programmatic changes, but it must be done in a certain way, and
	/// 	overall it is not recommended.
