  Specification of objects on which this tag is applicable. Normally, the applicability is determined by the presence of the respective policy rule(s) related to this tag (by assignments or global policy rules selectors). But we need more fine-grained approach when reporting on the tags. For example, we may need to consider only a subset of all projections (shadows) that were processed. Experimental. This may be a bad idea overall.
