Conformace statement and cardinality of property dcat:dataset do not match

In the Conformance statement, it is stated that there has to be at least one catalogue with at least one dataset.

"In order to conform to this Application Profile, an application that provides metadata MUST:

• Provide a description of the Catalogue, including at least the mandatory properties specified for the class Catalogue.
• Provide descriptions of Datasets in the Catalogue, including at least the mandatory properties for the class Dataset."

However, cardinality of dcat:dataset in the Catalogue class is 0..n instead of 1..n.
