See "C.3 Property Table: Part II", the fifth column of that table.

The OASIS (nee SGML Open) Exchange Table Model [1] that is one of the
most widely implemented ones includes table headers but not table
footers.  So in this case, it might not be "able to implement"
issues, but "already deployed software, interfaces, documents,
and user-education" issues that put table-footer in the extended
category.  Certainly, that is my position.

Table B5 says (for list-item-label) "extended; fallback: labels that 
break across multiple lines are treated as separate blocks before 
list-item-body."  I believe that is intended to mean that *some*
implementation of list-item-label (i.e., that described as the fallback)
must be implemented in all (e.g., basic) implementations, but the full
semantic (that also handles multi-line labels) is an extended feature.
