UMLNIEM3 — Define abstract elements

Table 7-3 lists several elements whose definition is simply Abstract. I would have thought a definition would be required even if it were abstract.

Document abstract elements in table 7-3

For each element in table 7-3 whose Note is currently Abstract, replace Abstract by the specification text that appears in the Description section for the corresponding element in clause 8.5. Keep the name of the element in italics but write the Note in normal text. Clarify that italics denotes abstract.
