libyang[0]: Not found node "diffserv-markings" in path.

[bam44555]

Is there a way to resolve this installation issue other than enabling UDPIP-BASED-CU-PLANE feature on o-ran-processing-element?

I am using o-ran-processing-element@2020-04-17.yang & o-ran-interfaces@2021-03-22.yang.

o-ran-processing-element@2020-04-17.yang installation is failing with the following error:
libyang[0]: Not found node "diffserv-markings" in path. (path: Schema location "/o-ran-processing-element:processing-elements/enhanced-uplane-mapping/uplane-mapping/up-markings/ipv4/upv4-dscp-name".)

o-ran-interfaces@2021-03-22.yang was installed without UDPIP-BASED-CU-PLANE feature enabled.

Module details below:

o-ran-interfaces
2021-03-22
urn:o-ran:interfaces:1.0
implement

o-ran-processing-element
2020-04-17
urn:o-ran:processing-element:1.0
implement

Thanks in advance.
