Schema With Multi Part Attribute

Hi,

I am wondering if it is possible to create a schema with a multi part attribute. In other words I want the value of the attribute to be a dictionary. For example I would have an attribute called "Application" which would have a value of:

{"name" : "Application Name", "active" : <True or False>}

The other way I was thinking about doing this was to just have a multi value string attribute that would be the names of the "applications" and if there was an entry then that "application" is active but the dictionary way just seems cleaner to me.

If this is possible an example of how to define the schema entry or a link to an RFC would be helpful.

Thanks,
