* <b>tooltipConfig is deprecated, use individual tooltip configuration attributes instead </b>
*
* Every Form UI component (in xhtml / css_xhtml or any other that extends them) can
* have tooltips assigned to them. The Form component's tooltip related attribute, once
* defined, will be applied to all form UI components that are created under it unless
* explicitly overriden by having the Form UI component itself defined with their own tooltip attribute.
*
* <p/>
*
* In Example 1, the textfield will inherit the tooltipDelay and tooltipIconPath attribte from
* its containing form. In other words, although it doesn't define a tooltipIconPath
* attribute, it will have that attribute inherited from its containing form.
*
* <p/>
*
* In Example 2, the textfield will inherite both the tooltipDelay and
* tooltipIconPath attribute from its containing form, but the tooltipDelay
* attribute is overriden at the textfield itself. Hence, the textfield actually will
* have its tooltipIcon defined as /myImages/myIcon.gif, inherited from its containing form, and
* tooltipDelay defined as 5000.
*
* <p/>
*
* Example 3, 4 and 5 show different ways of setting the tooltip configuration attribute.<br/>
* <b>Example 3:</b> Set tooltip config through the body of the param tag<br/>
* <b>Example 4:</b> Set tooltip config through the value attribute of the param tag<br/>
* <b>Example 5:</b> Set tooltip config through the tooltip attributes of the component tag<br/>
