In the Netconf version 5 the request looks like:

POST http://localhost:8181/rests/operations/sal-remote:create-data-change-event-subscription

with the payload:

<input xmlns="urn:opendaylight:params:xml:ns:yang:controller:md:sal:remote">
  <path xmlns:a="urn:TBD:params:xml:ns:yang:network-topology">/a:network-topology</path>
  <datastore xmlns="urn:sal:restconf:event:subscription">CONFIGURATION</datastore>
  <scope xmlns="urn:sal:restconf:event:subscription">BASE</scope>
</input>

and the result depends on the Accept header not Content-Type!

With Accept set to application/xml we successfully get:

<output xmlns="urn:opendaylight:params:xml:ns:yang:controller:md:sal:remote">
  <stream-name>data-change-event-subscription/network-topology:network-topology/datastore=CONFIGURATION/scope=BASE</stream-name>
</output>

The issue in not present. User has misconfigured his request (used wrong header parameter).
