Jena fails to parse valid RDF

[Andreas Kahl]

Hello everyone, 

I got this error while trying to load data from a URI to a Jena model:
http://viaf.org/viaf/32182557 (RDF-URL:
https://viaf.org/viaf/32182557/rdf.xml )

If I paste the rdf.xml to W3C's validator, it validates successfully.
(URL: source of https://viaf.org/viaf/32182557/rdf.xml ->
https://www.w3.org/RDF/Validator )

Is there any setting that should be used in order to make Riot more
tolerant to this?

The Jena version used is 3.13.1. 

Thanks for your advice. 

Best Regards
