Subject: Re: Attribute Array in JSON Request

Hi, In retrospect, I think I probably forgot. The profile is inconsistent in how I handle arrays. That said, now that I attempted to write a swagger definition, I realize that shortcuts like allowing an array to be a single-valued object does not save you much and makes your code much harder.
I and others in the TC agree. The extra code complexity isn't worth it to save a couple of octets here and there. Also, a future work item for the TC is a JSON profile for XACML policies and policy sets which would share a number of constructs with the JSON profile for the protocol. We would want to make the implementation easier by not having any options to output an object instead of an array of one object, but it would be messy if the protocol still allowed it. Consequently, the TC is proposing to remove from the JSON profile all the cases where the implementer is given the option to use an object instead of an array with only one object. Unless you particularly wanted to do it, Hal and I will take care of these edits for the JSON profile. To maximize interoperability, those of us with an existing implementation should stop using the option to send an object instead of an array as soon as it is practical to do so, but continue to accept a single object where an array is expected. Implementations of the revised JSON profile would not be expected to use or accept that option. We will also need new statements of use, which strictly speaking should be from implementations that don't ever send an object in place of an array. We will be starting the edits in a few days, so if anyone has concerns they should voice them now.
Did anyone get a chance to try the swagger I wrote?
I haven't tried it. Regards, Steven

I'm not so sure that is the error. You have various cases where fields that may take multiple values may be represented as a single object instead of an array containing a single object. Did you intend that this rule should also apply to the Attribute field but didn't make it explicit, or did you intend that the Attribute field always be an array?
