Andy Seaborne commented on JENA-1567:
-------------------------------------

I don't see a problem. Try creating an integer, print out model2 and it all 
works AFAICS.

xsd:string is special because (RDF 1.1) all strings without language tags are 
xsd:strings. xsd:string is not printed when output - it is not needed but "abc" 
is an xsd:string.

> TriX output serialized by jena will produce xml that uses the default 
> namespace.
> <trix xmlns="http://www.w3.org/2004/03/trix/trix-1/";>

> When the ReaderTrix class attempts to deserialize the xml the "datatype" 
> attribute namespace is not properly detected.
>  
> This appears to be in the  
> {{private String attribute(XMLStreamReader parser, String nsURI, String 
> localname)}}
>  
> The problem appears to be that parser.getAttributePrefix() returns an empty 
> string and parser.getAttributeNamespace() returns an emptry string (Not NULL) 
> so we don't call parser.getName().getNamespaceURI() to set the attrNS value 
> so the equality check fails and we throw an exception.
> I think that checking for "" should be added to the null check though " " 
> should also probably call the parser.getName().getNamespaceURI() method.
