Doubt about Definition of Done

Hi all,

I have a "detailed doubt" about how to interpret how Definition of Done is defined on the Scrum Guide (2013).

In page 15 we can see:
1. This is the definition of “Done” for the Scrum Team and is used to assess when work is complete on the product Increment.
2. If "done" for an increment is not a convention of the development organization, the Development Team of the Scrum Team must define a definition of “done” appropriate for the product.

I always thought that DoD is a tool used within by the Developmen Team to standardize and improve quality, but that first reference to the whole Scrum Team is misleading me a little bit.

How they I should answer the question "Who must conform the Definition of done?" The Development Team or the Scrum Team?

Thanks in advance.
