How do I get linked work item information via Predecessor _value in RPE?

I am using RPE to output scheduling aspects of EWM/RTC plans. I have a "predecessor(string)" element in the schema under workitem, but no element referring to "com.ibm..." which would suggest it is a link.
The output of "_value" (the only available schema element) within "predecessor(string)" is something like "_WjuaqzWKEfCfw77WRiG4qg". This seems like a possible component of a URL/URI, but if it is I do not know how to construct a URL from it.
Nothing for successor appears in the schema at all, or I would try the reverse approach.

So, my real question is how do I follow the predecessor link type to get to linked work item information? Is the element I've been looking at a dead end?
Thank you in advance for any assistance/direction you can provide!
