XML Messages generated by XI using namespace aliases...

Question

I have a question regarding the XML messages that are generated by XI as part of the mapping, etc.
I receive e.g. the following XML document in the payload of my message sent to a legacy system:
<ns1:ArticleRequest xmlns:ns1="http://www.basis.ko.com/XMLSchemas/ArticleRequest/2.0" function="retrieve">
     <ns1:ArticleNumber>109</ns1:ArticleNumber>
</ns1:ArticleRequest>
Unfortunately the system cannot handle the ns1: prefixes correctly and would prefer if the XML message were using the default namespace.
Can XI be configured to produce the XML using the default namespace (in case the interface has just one namespace this should be semantically identical)
<ArticleRequest xmlns="http://www.basis.ko.com/XMLSchemas/ArticleRequest/2.0" function="retrieve">
     <ArticleNumber>109</ArticleNumber>
</ArticleRequest>
and furthermore, is there a way to include the xsi:schemaLocation attribute in the resulting XML document?
like this:
<ArticleRequest xmlns:ns1="http://www.basis.ko.com/XMLSchemas/ArticleRequest/2.0" function="retrieve" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.basis.ko.com/XMLSchemas/ArticleRequest/2.0 ArticleRequest.xsd" >
     <ArticleNumber>109</ArticleNumber>
</ArticleRequest>
kind regards for your help,
Peter

Hi Udo,
I'm not sure how the XSL Mapping can remove the namespace alias and exchange it with default namespace. The xsl:copy-of just does a duplication of the selected node. Do you have any additional input on this one?
Regarding the second hint, 'manipulate the field XML namespace in the message type', I could not find a place where to do this - as I am using 'External Definition' (XSDs imported into XI). Still when I change the namespace I will always receive the prefix in front of each element.
Any additional help is highly appreciated.
regards,
Peter
