-Instance or meta attributes (`params` and `meta`) may contain
-a reference to another set of attributes. In that case, no other
-attributes are allowed. Since attribute sets' ids, though they do
-exist, are not shown in the `crm`, it is also possible to
-reference an object instead of an attribute set. `crm` will
-automatically replace such a reference with the right id:

-crm(live)configure# primitive a2 www-2 meta $id-ref=a1
-crm(live)configure# show a2
-primitive a2 apache \
-    meta $id-ref=a1-meta_attributes
-    [...]
-...............
-It is advisable to give meaningful names to attribute sets which
-are going to be referenced.
