Strange behaviour of XMLLiterals in RDF/XML

[Martynas Jusevičius]

Hey list,

I'd like to know why the following triple

  @prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> .
  @prefix awol: <http://bblfish.net/work/atom-owl/2006-06-06/AtomOwl.html#> .

  _:smth awol:xml '<div
xmlns="http://www.w3.org/1999/xhtml";><p>stuff<br/>more
stuff</p></div>'^^rdf:XMLLiteral .

serialized into RDF/XML produces escaped XMLLiteral:

<rdf:Description rdf:nodeID="A23">
    <awol:xml 
rdf:datatype="http://www.w3.org/1999/02/22-rdf-syntax-ns#XMLLiteral";>&lt;div
xmlns="http://www.w3.org/1999/xhtml"&gt;&lt;p&gt;stuff&lt;br/&gt;more
stuff&lt;/p&gt;&lt;/div&gt;</awol:xml>
  </rdf:Description>

However this one

  _:smth awol:xml '<div
xmlns="http://www.w3.org/1999/xhtml";><p>stuff<br></br>more
stuff</p></div>'^^rdf:XMLLiteral .

produces unescaped XMLLiteral, as expected:

<rdf:Description rdf:nodeID="A23">
    <awol:xml rdf:parseType="Literal"><div
xmlns="http://www.w3.org/1999/xhtml";><p>stuff<br></br>more
stuff</p></div></awol:xml>
  </rdf:Description>

Both <br/> and <br></br> are well-formed and equivalent in the XML
context, so why the difference in serialization?
I'm using Jena 2.6.4 and ARQ 2.8.7.
