Newspaper always a Periodical?

[TobiasNx]

Is newspaper a subset of Periodical therefore all Newspaper also have type Periodical?

I was stumbling over old and new records in ALMA/ALEPH, e.g.:

In Aleph Spiegel used to be a type:Periodical and a type:Newspaper. Now it is only a Newspaper.
They seem not to be mutual exclusive but are Newspaper a subset of Periodicals and therefore all Newspapers are Periodicals too?

We use bibo:Newspaper which is defined as Peridocal, see http://purl.org/ontology/bibo/Newspaper. Also, ZDB types the example (Der Spiegel) as periodical, see http://ld.zdb-services.de/data/204679-9.ttl
