Karen and others
The terminology of "sub-element" and "element sub-type" is used in the document that the Element analysis table supports:
This is archived. It has not been updated since 2009, although various submissions by the RSC Technical Working Group cover follow-up and development activities:
An element sub-type is a refinement of an element, and is represented in RDF as a sub-property of the less granular element.
A sub-element is a component of an element. The classic example is Publication statement, which has Place of publication, Publisher's name, and Date of publication as sub-elements. In DCAM/DCAP, the selection, sequence, delimiters, etc. of the sub-element values to provide a value for the "aggregating statement" element is specified by a Syntax Encoding Scheme. For example, MARC 21 uses SESs based on ISBD punctuation templates.
RDA uses RDF sub-classes to represent entity sub-types; for example, the entity/class Person is a sub-class of the entity/class Agent.
The RSC intends to review the element analysis and its presentation during the 3R Project. The terminology itself probably originates in developments following the Data Model Meeting at the British Library in 2007 (http://www.bl.uk/bibliographic/meeting.html). The distinction is useful.

Hi, Judy. One of the elements here is listed as:
Aggregating or Super Element
The name of the element that aggregates a sub-element or is the
super-type of an element sub-type.
Is this the same as a class/super-class in RDF? If not, can you (or
someone) explain the difference?
