As part of overall genius Karaf 4 testing, today I'm seeing the DOMSchemaService not coming up:

opendaylight-user@root>feature:install odl-genius-ui

opendaylight-user@root>diag
sal-schema-service (218)
------------------------
Status: GracePeriod
Blueprint

Missing dependencies:
(&(|(type=default)(!(type=*)))(objectClass=org.opendaylight.mdsal.dom.api.DOMSchemaService))

and, eventually, this:

opendaylight-user@root>diag

There is nothing in the LOG.
