Action 237: Do we need the lengthKind 'endOfParent' restriction for local groups?
by Steve Hanson 02 Dec '13

02 Dec '13

237 Public comment: Do we need the lengthKind 'endOfParent' restriction for local groups? (Steve) 5/11: http://redmine.ogf.org/boards/15/topics/51. Stops such an element being wrapped in a local group. It looks like this was added to make checking easier. Really the restriction is that the element is "last in the box", and could in principle have surrounding intermediate sequences or implicit choices. Need concise language to express this. 12/11: Need language written. ... 26/11: With Steve, no progress. Attached is an updated version of the description for 'endOfParent', which attempts to make the concept clearer.

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.
