UML14 — Figure 8 (Semantics, p. 44)

Summary: The Semantics document states that "a Component is a subclass of Class" (p.
45) and "a Node is a subclass of Class" (p. 46). However, Figure 8
(Semantics, p.44) shows both Component and Node as subclasses of
Classifier. Further, the Notation Guide states that "A component symbol
maps into a <<component>> stereotype of a Class or Object" and similarly
for a node symbol. My understanding is that the text of the Semantics
document is correct, and the diagram and Notation Guide should be changed
to conform to this.

Fixed in UML 1.2.
