[Rdfapi-php-interest] xml: namespace declaration in SPARQL output gives error

[Onno P. <onn...@gm...>]

 When using SPARQL netapi, when outputting an entire model or outputting a
CONSTRUCT query the output starts with:
<rdf:RDF
   xml:base=3D"http://www.15926.org/2006/02/dm#
   xmlns:rdf=3D"http://www.w3.org/1999/02/22-rdf-syntax-ns#"
   xmlns:xsd=3D"http://www.w3.org/2001/XMLSchema#"
   xmlns:rdfs=3D"http://www.w3.org/2000/01/rdf-schema#"
   xmlns:owl=3D"http://www.w3.org/2002/07/owl#"
   xmlns:xml=3D"http://www.w3.org/XML/1998/namespace"
   xmlns:dc=3Dhttp://purl.org/dc/elements/1.1/
... etc

This works fine in Firefox, but in Internet Explorer an error message comes
up:
---------------------------------------------------------------------------=
-----
The XML page cannot be displayed
Cannot view XML input using XSL style sheet. Please correct the error and
then click the Refresh button, or try again later.
The namespace prefix is not allowed to start with the reserved string "xml"=
.
Error processing resource 'http://localhost/be...
   xmlns:xml=3D"http://www.w3.org/XML/1998/namespace"

The xml: namespace is not required to be declared (I think). It is not part
of the model's namespaces stored in the RAP namespaces table, neither does
it come up anywhere in the SPARQL sources. I am not able to solve it
quickly.
