Add Contextual Help in AEM

Request for Feature Enhancement (RFE) Summary:	Improve UX by adding contextual help/tooltips/instructional help within AEM.
Use-case:	Technical writers currently find it difficult to know the purpose of many icons, buttons, and menu items when navigating the AEM UI as they don't have any/sufficient tooltips or instructional help.
Current/Experienced Behavior:
Improved/Expected Behavior:	Clarity regarding the purpose and meaning of: Menu items. The distinction between "Experience Fragments", "Assets", and "Content Fragments". Global vs iLX Profile.  It would be helpful to have an easily accessible link to Adobe's documentation within AEM.

@AvrilDu how it is different from adding value in dialog

<dialog xmlns:sling="http://sling.apache.org/jcr/sling/1.0" xmlns:cq="http://www.day.com/jcr/cq/1.0" jcr:primaryType="cq:Dialog"> <items> <textfield name="./tooltipText" fieldLabel="Tooltip Text" description="This is the tooltip text that will be displayed when the author hovers over the field." /> </items> </dialog>
