The bat file wasn't quite right - it printed "Succeeded with no validation
errors" even when there were errors. Here's the correct way to do it:
---------------------------------------------
@ECHO OFF
call echo.
call echo validate that instance.txt is a valid instance of the data format
call ../../../dfdl/bin/daffodil.bat --version
call ../../../dfdl/bin/daffodil.bat parse -s data-format.dfdl.xsd --validate=on
-I null instance.txt
if %errorlevel% == 0 (
echo Validation Succeeded
) else (
echo Validation Failed
)
---------------------------------------------

Thank you Steve! That works great.
Here is my validate.bat file (for those interested):
---------------------------------------------
@ECHO OFF
call echo.
call echo validate that instance.txt is a valid instance of the data format
call ../../../dfdl/bin/daffodil.bat --version
call ../../../dfdl/bin/daffodil.bat parse -s data-format.dfdl.xsd --validate=on
-I null instance.txt
if errorlevel 0 echo Succeeded with no validation errors 1>&2
---------------------------------------------

Daffodil currently only outputs anything if there are problems (e.g.
parse fails, validation error found). Silence means success.
Daffodil does change the exit code depending on success/failure. Zero
means success, 1 means failure.
So if you want a success message, you can check the return code and
print a message when it's zero. I'm not a Windows person, but I /think/
adding this to the end of the bat file should work:
if errorlevel 0 echo Succeeded with no validation errors 1>&2
