Domain Functional Requirements are what most people think of when they think IT:AD:Functional Requirements.

Domain Functional Requirements describe the Functions a System performs in order to assist the Business Domain.

That said, it's important to understand that there are also IT:AD:System Functional Requirements to describe the System's functions that are not part of the Business Domain. These IT:AD:System Functional Requirements are defined in the IT:AD:Supplemental Specifications.
