> For the XML example of PROV-Dictionary we ran into some trouble when

> Since we use real-world dbpedia URIs as example, there were some that
> could not be turned into a valid QName due to its character restrictions.
> Therefore, we had to find a workaround. The workaround is to add a valid
> NCName (derived by removing the invalid characters) as a fragment, and
> split the URI after the # symbol. The first part of the URI is then used to
> override the dbpedia: prefix in the element that uses the URI as an
> identifier, and the valid NCName is used as the LocalPart of the QName.
> This is in conformance with the guidance given in the the RDF/XML Syntax

> The only thing that raises some doubt is the use of the nonexistent
> fragment, but since the URI still resolves, this is worth it in my opinion.
> We added a remark explaining this construct to the end of the example.
