In the service definition file, a resource can not be added to the list of dataMaskDef resources without also declaring it as a resource for access policies. Plugins should have the flexibility to define a resource for column masking policies only.
For example, a plugin may only allow the creation of access policies at the table level. Currently, for this plugin to add column masking policies with a 'column' resource, 'column' would also have to be added to access policies.
This Jira requests the removal of this requirement, or at least the ability to hide the resource in access policies.
