From Henry Yu:

Our CCVPN - Transport Slicing integration test has encountered a problem which may be related to a AAI schema change introduced in  v20/v21.  When v20 schema was introduced [1], the following top-level nodes under "network" namespace, which used to exist in v19 schema, had been removed:

<xs:element ref="tns:label-restrictions" minOccurs="0"/> <xs:element ref="tns:unis" minOccurs="0"/> <xs:element ref="tns:te-link-attributes" minOccurs="0"/> <xs:element ref="tns:interlayer-attachments" minOccurs="0"/> <xs:element ref="tns:tunnel-termination-points" minOccurs="0"/>

This is causing the CCVPN/Transport Slicing operations to fail, as we can no longer create these top-level nodes in AAI.
