Some of the properties in datasource subsystem are disabled to be set by expression. It would be good if all attributes could be set by expression if possible.

Namely these are those which sets "expressions-allowed" as false

• driver
  • driver-class-name
  • driver-module-name
  • driver-xa-datasource-class-name
  • module-slot
  • jdbc-compliant
  • profile
• data-source
  • allow-multiple-users

This issue came alongside with testing EAP7-467 which asks for allowing expressions in datasource subsystem, especially for attribute 'enabled'.
