Requesting the control information structure — <info user='{user}' lang='{lang}' path='{path}' />
The information request returns the hierarchical structure of the configuration provided by the node. The request usually does not contain the "path" attribute and extends to the entire node, although in complex cases of requesting a part of the information tree, the path of the element of the branch from which to receive the configuration can be specified.
