This explains why one would use rdfs:label and why it is used in Example 2, but not why rdfs:label is used in Example 1 or 6, where bf:mainTitle would also apparently work. Is the point in these examples that rdfs:label can be used under bf:title without declaring whether or not the title given is a bf:mainTitle, which may not have been determined?
