Use in the InCommon Federation

When working with InCommon Participants, an email address should only be used as a mean of contact. It is not a suitable user identifier (see: Why is email address not an appropriate user identifier?).

mail is a required attribute in the REFEDS Research & Scholarship (R&S) entity category.
