I think we need to be careful about mandating that Full Registries MUST 
harvest any registry type.
Suppose that someone puts up a publishing registry for a particular 
specialist resource type for which they have defined their own set of 
extension schema. The schema are horrendously complicated (even by IVOA 
standards) and will not translate easily into a relational structure. 
Unfortunately their local Full Registry is based on a relational db and 
so will not harvest them. Of course, in this case, the publishing 
registry could find another Full Registry that could contain their 
contents but the point is that Full Registries are not necessarily 
full.
