UML22 — Section 8.3.2 sub-section "Notation" starting on page 149

Issue:
The use of the keyword <<component>> on all diagrams in this section is inconsistent with standards used elsewhere in the spec (for example the notation shown in the Interfaces package). When a shape has the small component icon showing, the keyword is not required and arguably should not be shown.

Rationale:
The diagrams imply that both the icon and the keyword should always be shown. This is of course not the case. As it is, some tools vendors not only accept this incorrect implication but some have also mistaken the keyword for a stereotype. It would be much clearer if the keyword were only shown on component boxes that did NOT have the plug icon in them.

Note that the notation shown on Page 152 (first page of section 8.4) is "correct" - i.e. much more appropriate, and less likely to mislead. On the other hand that shown on page 153 is "incorrect".

The classifier notation of a component is defined showing the keyword "component" and optionally the component icon in the upper right corner. All examples in the component chapter of the UML 2.2. (ptc/2008-05-05) show the component with keyword and icon. However table 8.1 shows a component with an icon and without the keyword. This presentation option must be added to the component definition.
