I need my BizTalk map to stop xml: lang to ns1: lang conversion

Question

I have a map in BizTalk 2009 that converts some data into an XML document that will be sent to another system. The target schema includes some elements with attributes xml:lang. BizTalk generates them as ns1:lang. The target system requires the use of a prefix xml.

Here is a simplified example showing what BizTalk does:

sample.xsd

<xs:schema targetNamespace="http://example.com/"
           xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <xs:import schemaLocation="common.xsd"
             namespace="http://www.w3.org/XML/1998/namespace" />
  <xs:element name="example">
    <xs:complexType>
      <xs:attribute ref="xml:lang" />
    </xs:complexType>
  </xs:element>
</xs:schema>

common.xsd

<xs:schema xmlns:xml="http://www.w3.org/XML/1998/namespace"
           targetNamespace="http://www.w3.org/XML/1998/namespace"
           xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <xs:attribute name="lang" type="xs:language" />
</xs:schema>

Card output example

<ns0:example xmlns:ns0="http://example.com/"
             xmlns:ns1="http://www.w3.org/XML/1998/namespace"
             ns1:lang="en-US" />

Is there a way to convince BizTalk to use a prefix xml?

Answer 1

As far as I know, there is no built-in way to achieve this.

There are, however, two solutions that I see:

XML StyleSheet

- xsl, XML :

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                xmlns:ns1="http://www.w3.org/XML/1998/namespace"
                ...
                >
...
<xsl:attribute name="ns1:lang">
...
