Defines a result from an employee performance management (EPM) process or "appraisal". An appraisal typically consists of a number of sections, including an overall rating or score, competency ratings, objective ratings, and other ratings (e.g., "core values" is an example of a section within some appraisals outside of the competency or objectives section). Also includes result metadata, such as appraisal dates, "prepared by," etc. Note that EPM is an HR-XML approved abbreviation for "Employee Performance Management".
