component attribute inheritance

Except for installPath and limitToHostSet, component attributes are not inherited.

The installPath attribute is inherited, and may not be overridden by derived components. Note, however, that the base component may use component variables in specifying its value, and the value of these variables may be overridden.

The limitToHostSet attribute is also inherited, and may be overridden by derived components only if the base component did not specify a limitToHostSet. Note that since the limitToHostSet value names a mutable, client managed entity, the relation of host set can not be reasoned about in the same way as platforms.

The platform attribute is not inherited. However, the platform value of a derived component may be no more general than that of the base component. If the platform is unspecified in a derived component, then it also must be unspecified (or specified as “any”) in the base component.
