Daffodil hardcoded the namespace prefix?

[Costello, Roger L.]

Hi Folks,

Instead of using "dfdl" as the namespace prefix, I used "x"

xmlns:x="http://www.ogf.org/dfdl/dfdl-1.0/";

And I changed all namespace qualifiers from "dfdl:" to "x:"

Per the XML namespace specification this is perfectly legal. However, when I 
ran my DFDL schema I got this error:

[error] Schema Definition Error: Invalid dfdl annotation found: x:format

Huh?

Did Daffodil hardcode the namespace prefix? That is, if any namespace prefix 
other than "dfdl" is used in a DFDL schema, Daffodil fails?
