/**
 * The state of a resource.
 * 
 * The state represents the OSGi installer's view. It might not
 * reflect the current state of the system. For example if a
 * bundle is installed through the OSGi installer, it gets the
 * state "INSTALLED". However if the admin now deinstalls the
 * bundle through any other way like e.g. the web console,
 * the artifact still has the state "INSTALLED".
 * 
 * The state "INSTALLED" might either mean installed or
 * if the attribute {@link TaskResource#ATTR_INSTALL_EXCLUDED}
 * is set on the resource, the resource is excluded from
 * installation. It gets also marked as "INSTALLED" in order
 * to mark it as "processed" for the OSGi installer.
