Create a single registryObject node. Each set has its own structure but they all have an attribute of group, a key node and an originatingSource node. The newly created node will be used as the working node.

\param $group string, group attribute of the new registryObject node .
\param $key string, key node, used as an identifier.
\param $originatingSource string, an url of the data provider.
