The arguments field is a map so you could do:



Is this the right approach for passing the SEL context though? We don't 
pass ACL permissions for queues that way, at least at present. Would a
config file that defines any necessary mapping work?

I would prefer to keep SELinux specific stuff within an ACL 
implementation plugin if at all possible.
