<component>
The <component>
element describes the component of the product that this
topic is concerned with. For example, a product might be made up of many components, each
of which is installable separately. Components might also be shared by several products so
that the same component is available for installation with many products. An implementation
may (but need not) use this identification to check cross-component dependencies when some
components are installed, but not others. An implementation may also (but need not) use the
identification to make sure that topics are hidden, removed, or flagged in some way when
the component they describe isn't installed.
