My conclusion from this is that the RDF specification should be changed, so that an application would be able to demand that certain nodes are blank.

And despite of that it is not already in the RDF standard, it seems that most of implementation already provide support for this: Using an RDF library I can tell which nodes are blank and which are not.

Again: I demand to change the RDF specification. The rationale: Users should be able to construct an RDF file in such a way that loading more RDF files would not break its consistency. It is important.
