notation question

[Ken in Nashua]

Dear Shiro Users,

Is this notation legal to do ?

configuration.add(factory.createChain("/perms/create/**").add(factory.perms(), 
"*:create:*").build());

or should I go with 

configuration.add(factory.createChain("/perms/create/**").add(factory.perms(), 
"*:create").build());

Thanks for any best practices advice.

Ken
