This class of cmavo includes but is not limited to default specification modifiers as well as default-value-referencing pro-sumti; it is a subset of the set of all cmavo. "Class" in the definition does not necessarily mean selma'o. Proposed short rafsi: -zic-. For "default specification modifer" use gafyzmico; for "default-value-referencing pro-sumti" use sumyzmico or zicysu'i.
