XDI collection as attribute

Andy recently mentioned a bug in the XDI graph editor where collections are not represented using a diamond (attribute).

As I'm trying to determine the appropriate pattern for collections, I started reading the XDI ABNF and came up with some questions: what type of collections *must* be represented as an attribute?

For instance, should we represent an authority-collection (i.e. a person-collection or a legal-collection) as an attribute?

Also, can someone confirm https://wiki.oasis-open.org/xdi/XdiAbnf is up to date?

Thanks,

Hubert
