For a standalone server one can always pull the running configuration from the configuration dir, and can also use the root resource 'take-snapshot' op to persist a different file with the current content. But for a domain server there is no persistent form of the server's effective config and the 'take-snapshot' op is not exposed.

The 'read-config-as-xml' op was meant to help with this but unfortunately the CLI takes the output and escapes every quote before displaying it, which makes the output unusable without further manipulation.

Perhaps a high-level read-config-as-xml op?
