still no need for fn:error
by Mike Beckerle 03 Aug '16

03 Aug '16

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> -- Mike Beckerle | OGF DFDL Workgroup Co-Chair | Tresys Technology | www.tresys.com

DFDL's approach vs tradition parser-generators
by Garriss Jr., James P. 25 Nov '13

25 Nov '13

Traditional parser-generators and DFDL generate parsers. At a high level, how would you summarize the difference in approaches between these two? TIA "You're only paranoid if they're not out to get you." (JD)

Re: [DFDL-WG] possible editorial issue - Schema Definition Warning
by Steve Hanson 13 Nov '13

Jonathan Feel free to add your original point, namely that Schema Definition Warning only appears once, as a public comment. Regards Steve Hanson Architect, IBM Data Format Description Language (DFDL) Co-Chair, OGF DFDL Working Group IBM SWG, Hursley, UK smh(a)uk.ibm.com tel:+44-1962-815848 From: Steve Hanson/UK/IBM To: "Cranford, Jonathan W." <jcranford(a)mitre.org>, Cc: "dfdl-wg(a)ogf.org" <dfdl-wg(a)ogf.org>, dfdl-wg-bounces(a)ogf.org Date: 05/11/2013 16:01 Subject: Re: [DFDL-WG] possible editorial issue - Schema Definition Warning RecoverableError is not appropriate here. The problem is with the schema not the data.

That is, would the following convey the originally intended meaning better? Note: Unrecognized DFDL properties or property values can produce a recoverable error, and an implementation can attempt to process data despite the error. IIRC, this section on specific errors was added *before* recoverable errors were added to the spec.
