• class="accTooltip" : The bootstrap class name that specifies an accessible tooltip.
• data-src : The resource path and pointer to the ID attribute of the tooltip container element. If set, data-internal should be blank or not included.
• data-internal : The ID attribute of the tooltip container element within the same document.
  Syntax of tooltips within the same document:
  <div class="hidden">
<div id="tooltipIdContent">
...
</div>
...
</div>
  If data-internal is set, data-src should be blank or not included.
• data-role : The role name that is conveyed to screen reader users as beginning and ending boundary text for the new content. "Tooltip" is set by default if no value is specified.
• data-autoposition : The autoPosition override, which dynamically positions the new content relative to the triggering element. This reflects the autoPosition property documented within AccDC, and may be a value between 0 and 12. The default is 3 if left blank or not included.
• data-offsetleft : The offsetLeft override, which dynamically positions the new content relative to the triggering element. The default is 10 if left blank or not included.
• data-offsettop : The offsetTop override, which dynamically positions the new content relative to the triggering element. The default is 0 if left blank or not included.
• id : The unique ID of the element. This value is also registered as the ID of the tooltip AccDC Object, making it possible to invoke the object programmatically.
