Question:
Fiware: How to create lazy attributes through IDAS UltraLight

Description:
I'm using the IoT Agent Ultra-Light module to communicate with the Orion context broker. I can create services and devices and I have checked that the observations reach the context broker too.

curl -X POST XXX.XXX.XXX.XXX:8090/iot/services \
-i \
-H "Content-Type: application/json" \
-H "Fiware-Service: sanitysrv " \
-H "Fiware-ServicePath: / sanitysspath " \
-d '{"services": [

]}'

curl -X POST XXX.XXX.XXX.XXX:8090/iot/devices \
-i \
-H "Content-Type: application/json" \
-H "Fiware-Service: sanitysrv" \
-H "Fiware-ServicePath: /sanitysspath" \
-d '{"devices":[{"device_id":"CE_BDM_3","protocol":"PDI-IoTA-UltraLight", "commands": [], "attributes": [

]}]}'

My problem is that I don´t know how to register a device that contains lazy attributes, and I haven´t found any documentation with related examples. The examples from other IoT Agents that I have tried are not working here.

¿How can it be done?
