Ah! Excellent explanation.
Thanks Steve! /Roger -----Original Message----- From: Steve Lawrence <[email protected]> Sent: Monday, August 26, 2019 12:41 PM To: [email protected] Subject: [EXT] Re: Why do I get this warning message: DFDL property was ignored: representation="text" Since it never makes sense to have a string with representation="binary", when the type is xs:string the representation is always implied to be "text". We don't even bother looking at the value of representation--it's just completely ignored. A new feature in Daffodil 2.4 warns when properties are ignore, so you now get a warning when representation is defined on string elements. Functionally, it's exactly the same as in 2.3, you just now get a warning. To get rid of the warning, you can either turn it off by disabling the "ignoreDFDLProperty" warning, or you can just remove the dfdl:representation="text" property from that element. I'd recommend the latter as it is actually pretty good at finding legitimate bugs in schemas. Note that for hexBinary, the representation is always implied to by "binary", so you also never need representation on elements with xs:hexBinary types.
