SAPD: Missing inherited attributes from CPD
According to section 22.214.171.124 of IFA014:
"A Sapd inherits from the corresponding Cpd Class [...] All attributes of the Cpd are also attributes of the Sapd"
These attributes are specified on section 126.96.36.199 of IFA011 and include a description, the layer protocol, the CpProtocolData, the trunkMode and the id of a security group rule. However, these attributes seem to be missing on the SAPD YANG definition so they cannot be specified at the NSD level.
