redeclaring xmlns:xsi in soap message

[Ex...@nokia.com]

Hello,

My question relates to the declaration of
xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance" in multiple points in
a SOAP XML document.  Consider one of our SOAP messages below.
Our SOAP engine is an XML processor.  In order to support interacting with
Apache 2.0 clients we apply XSL via Oracle XSLT to transform the XML.
Considering the
declaration of the <attributelistns:AttributeList> element we have noticed
is that the
resultant XML redefines the xsi namespace.  This appears to be benign and
Apache 2.0
processes the request fine but is it storing up problems for the future ?

Thanks

Regards,

Shaun O'Hagan
