---------------------------------------

             Summary: TDML test file cannot specify xmlns="" on the tdml:defineSchema element
                 Key: DAFFODIL-2618
                 URL: https://issues.apache.org/jira/browse/DAFFODIL-2618
             Project: Daffodil
          Issue Type: Bug
          Components: TDML Runner
    Affects Versions: 3.2.1
            Reporter: Mike Beckerle


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:

 
{code:java}
<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>
{code}
 

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.
