Since this text is a general introduction, not a definition related immediately to the schema, I propose this wording, which takes into account that there might be alternative term types, replacing the current sentence quoted in the spreadsheet.

An agreement includes information on the agreement parties and a set of terms. The terms MAY comprise one or more service terms and zero or more guarantee terms specifying service level objectives and business values associated with these objectives.
