Here's the example as suggested by Jonathan of how to issue an error that I
previously was suggesting needed fn:error. I'm convinced this is sufficient
and we can avoid the need for fn:error now.
<xs:element name="magic_number" type="ex:uint32" dfdl:byteOrder="bigEndian">
<xs:annotation>
<xs:appinfo source="*http://www.ogf.org/dfdl/*<http://www.ogf.org/dfdl/dfdl-1.0/>
">
<dfdl:assert
test="{ (xs:unsignedInt(.) eq *dfdl:hUInt('0xa1b2c3d4')*) |
(xs:unsignedInt(.) eq *dfdl:hUInt('0xd4c3b2a1')*) }"
message="{ fn:concat(
'Magic number ',
dfdl:hexBinary(dfdl:unsignedInt(.)),
' was not 0xA1B2C3D4 (for bigEndian) or 0xD4C3B2A1
(for littleEndian).' }" />
<dfdl:setVariable ref="ex:bOrd">{ xs:unsignedInt(.) }<dfdl:setVariable>
</xs:appinfo>
</xs:annotation>
</xs:element>
