Hi all,

I would suggest the following response.

It is correct that: A bundle is a named set of provenance descriptions 
It is also correct that section 2.2.3 indicates that many types of 
collections exist, including sets.
However, section 2.2.3 states: A collection is an entity that provides a 
structure to some constituents, which are themselves entities

In PROV, provenance descriptions are not given identifiers and are not 
regarded as entities.
Hence, a PROV bundle is not a PROV collection.

*/Suggested change/*: A collection is an entity that provides a 
structure to some constituents that MUST themselves be entities.

Thoughts, comments?

> A bundle (2.2.2) is a set of provenance descriptions, and a set is a type of collection (2.2.3). Therefore, it follows that a bundle is a specific type of collection (where the members of the collection are called "descriptions", as in section 5.4). This should be stated explicitly. Furthermore, since a bundle is a specialized collection, the spec would read better if their order in the document was reversed.
