| * A HostedCapability is a Capability where the {@link #getResource()} method |
| * returns a Resource that hosts this Capability instead of declaring it. This |
| * is necessary for cases where the declaring Resource of a Capability does not |
| * match the runtime state. For example, this is the case for fragments attached |
| * to a host. Most fragment declared capabilities and requirements become hosted |
| * by the host resource. Since a fragment can attach to multiple hosts, a single |
| * capability can actually be hosted multiple times. |
