fetchClassificationSchema

Fetches ClassificationSchema when PortalInfo.hasClassificationSchema is true. Returns the ClassificationSchema if the organization administrator has enabled it. The schema supplies classification metadata needed to correctly display item classification markings and banners (including colors and text) which are derived from the organization's primary classification attribute. If PortalInfo.hasClassificationSchema is false, the returned Result object will contain a Throwable describing the error. If the portal is not already loaded, it will be loaded automatically.
