[CONNECT C++] Find Associated Element

I've created a text element and associated it with a target element using TextHandlerBase::SetupOffsetAssociation.  That works fine.

Now, in a separate operation, I want to find an associated text element from that target.  That is, I locate the target element, then I want to find its associated elements.  Then sift those associated elements to find my text element.

How should I go about getting and following an associative trail?
