Description

The preferred style for writing a DFDL schema uses the default namespace for the XML schema namespace, so as to avoid having to put a prefix like "xs:" on every element. 

The prefered style for writing a TDML test file similarly uses a default namespace for the TDML namespace so as to avoid having to put a prefix like "tdml:" on every element.

Combining these two ideas, one would like to be able to embed a DFDL schema within the TDML file by way of this:

 

<tdml:defineSchema name="mySchema"
  xmlns="http://www.w3.org/2001/XMLSchema"  
  elementFormDefault="unqualified">
  .... schema here. Note that no "xs:" prefix is needed....
  <element name="foo" ..../>
</tdml:defineSchema>

 

This doesn't work however. Something about the way the embedded schema is removed and placed into a separate schema temp file for compilation makes namespace assumptions and doesn't tolerate the xmlns default declaration.
