Metadata adquisition using the library

[DavidCendan]

I saw that each service is used to extract a part of the information of the camera (media, events, analytics...), but in the ONVIF documentation you can see that there is also an xml file containing the information of the intellingt events (if there is any) programed in the camera.
Is there any feature capable of obtaining this kind of information or its just simply not accesible by ONVIF/SOAP?
