Subject [jira] [Created] (JENA-170) hexBinary whitespace issue

hexBinary whitespace issue

                 Key: JENA-170
             Project: Jena
          Issue Type: Bug
          Components: ARQ, Jena, RDF/XML
         Environment: 2.6.4
            Reporter: Henry Story

As I understand, initial and final white spaces in xsd:hexBinary in xml should be ignored
because of the whitespace facet.

With Jena 2.6.4 this is not the case, as shown by the test below. 
I found that in Clerezza when using the graph api, so this is a problem even when one does
not use SPARQL.
Removing the white space solves the proble. 

xsd:hexBinary is already a very fragile encoding. Making it this fragile is bound to lead
to issues in communication.
The same is true with the N3 encoding.

hjs@bblfish[0]$ cat q1.sparql 
PREFIX : <http://me.example/p#> 
PREFIX xsd: <> 

  ?S :related "AAAA"^^xsd:hexBinary .

hjs@bblfish[0]$ cat c1.rdf 

<rdf:RDF xmlns="http://me.example/p#"

    <rdf:Description rdf:about="http://me.example/p#me">
        <related rdf:datatype="">

hjs@bblfish[0]$ arq --query=q1.sparql --data=c1.rdf
