The spec says:
6.5 Request Parameters
To retrieve a subset of the attributes in a resource, the Consumer MAY use the ‘select_attr’ query parameter in conjunction with the HTTP GET
a) Can we add this (or a similar filter) the collection resources in such a way that it relates to the attributes of the entities within the collection, not to the collection itself.
b) Given that if you leave off the uri, the attribute-filtered collections can contain duplicates we need to define the behaviour around duplication. It would be helpful to have a version that shows only non-duplicated values so you can retrieve the set of possible values for an attribute (a kind of SELECT DISTINCT/Group By). We need this functionality in the UI to build filters.
