    which matches anything with a data-help attribute and therefore powers
    the "HTML Attributes" method.

    This method of using JavaScript allows for tremendous flexibly
    annotating the DOM with help items, even after it has been
    rendered--perhaps by other templates altogether, making it attractive as
    a mechanism for users to annotate aspects of RT--however it has been
    installed for them, including any and all extensions--simply by
    inspecting what is rendered to the browser and writing the appropriate
    rules. Importantly, these rules can usually be added to one place (e.g.
    in a page callback somewhere) so they do not need to overlay virtually
    every template in RT just to add help icons throughout.

   Help Selector Rules
    A help selector rule is a JavaScript object with the following keys:

    *   selector - *String*

        Required. Defines which DOM elements should receive a help icon. Can
        match 0, 1, or many elements. Selectors matching 0 elements have no
        impact on the DOM.
