Is there support for adding and extracting record-matches and smart-matches in the Geni API

I was wondiring about how I can access the source information from the Geni API...

Am I correct when I think that will NOT get the information about related documents when I receive a Profile structure

https://www.geni.com/platform/developer/help/api?path=profile&version=1

Can I get (and update) this information through the Documents interface ?

https://www.geni.com/platform/developer/help/api?path=profile%2Fdocuments&version=1

And will this include the record-matches and smart-matches connected to each profile?

Since I can actually get info about all other profile information (including photos) from the Profile structure, I was thinking that I should be able to get a list of document-xrefs as well from the Profile interface?

If I need to call the documents interface explicitly I will do so. I just want to make sure first.
