Define a Visio QuickInfo in DatadiagramML
<p>My program is outputting a chart as a VDX file to be viewed with Microsoft Visio (2013). In Visio a Shape can have a QuickInfo which is like a tooltip. How can I add such a QuickInfo or any other tooltip for a shape in the VDX file? VDX uses the XML schema DatadiagramML.</p>

<p>For reference I always use this <a href="http://m8y.org/Microsoft_Office_2003_XML_Reference_Schemas/Help/html/vixmlconSchema.htm" rel="nofollow">DatadiagramML schema overview</a>, because Microsofts own references load too slowly. Either way I rarely find what I'm looking for there.</p>
