CLI: xa-data-source add command does not allow to specify xa-datasource-properties

It seems that CLI xa-data-source add command does not allow to specify xa-datasource-properties. As having non empty xa-tadasource-properties map is mandatory, enabling such datasource fails:

[standalone@localhost:9999 xa-datasource-properties] xa-data-source add --name=TestXADS --jndi-name=java:jboss/datasources/TestXADS --driver-name=h2
[standalone@localhost:9999 xa-datasource-properties] xa-data-source enable --name=TestXADS
