xml:space attrbiute in XML-2-Object binding?

Dear list,

Has anyone made an XML-to-object binding that defines xml:space
attribute (that defines how whitespaces are handled) to be used in XML
documents? I tried the following two ways to include this attribute in
schema:

<object name="text" smalltalkClass="MyText">
  <attribute name="xml:space" aspect="xmlSpace" ref="xsd:string" />
</object>

or

<object name="text" smalltalkClass="MyText">
  <attribute aspect="xmlSpace" ref="xml:space " />
</object>

Both of these failed when loading the binding because the qualifier
"xml" was not found among defined namespaces. Furthermore, defining such
namespace by oneself is - obviously - not allowed either.

So, any ideas how to include this attribute?


With best regards,
