Setting value to 'Feature Types to Read' from Publish parameter

I have two workbenches. First one will gather some feature type names and use workspace runner to call second workbench which should read only selected feature types. I found i can send these values via published parameter.

 

 

But i do not know proper format of listing these names in publish parameter for

 

'Feature Types to Read' that can be understood by oracle spatial reader.

 

 

Please let me know how to handle this problem?

 

 

Thanks,
