I'd say it depends on context and packaging. If the basic distribution of the language includes a library for something, it makes sense to say that it's included in the language. If you have to download a separate library and install it to get the functionality, it doesn't make sense to say it's included in the language.
With Perl, you can download a library supporting almost anything, but only a limited number of things are included in the standard distribution of Perl.
It's all a matter of whether you can count on the thing being there or not, in a typical installation.
Pike 7.6 adds RDF and OWL support, too.

There is at least one more noteworthy addition in Pike 7.6: the support for the semantic web formats RDF and OWL.
