emptyValueDelimiterPolicy clarification
by Garriss Jr., James P. 31 May '13

31 May '13

This property specifies whether the initiator/terminator much be present if the element is empty. But the mere presence of this property does not specify that the element can be empty, right? IOW, I still have to describe that the element can be empty. That right?

[dfdl] initiatedContent w/o initiators
by Garriss Jr., James P. 30 May '13

30 May '13

Spec says: It is a schema definition error if any children have their dfdl:initiator property set to the empty string. Does that include a sequence with a hiddenGroupRef? For example, part of a schema for email headers is this: <xsd:choice dfdl:initiatedContent="yes"> <xsd:element ref="Date"/> <xsd:element ref="From"/> <xsd:element ref="MessageId"/> <xsd:element ref="Subject"/>  <xsd:sequence dfdl:hiddenGroupRef="UnwantedHeadersGroup"/> </xsd:choice> Date, From, and the other headers are all elements with initiators, but UnwantedHeadersGroup does not have an initiator (because I don't know it a priori). Should this throw an error in a DFDL implementation? I suspect it should, though I hope it shouldn't.

DFDL support for XML schema elements or attributes
by Alonza Mumford 30 May '13

30 May '13

I've looked over the DFDL 1.0 specification and I have a few questions regarding the inclusion of certain XML Schema elements or attributes. Does anyone know as to whether the following elements are supported in DFDL 1.0: - xs:extension - xs:list - xs:all - xs:any - xs:anyAttribute - xs:field - xs:key - xs:keyref - xs:selector - xs:unique Does anyone know as to whether the following elements are supported in DFDL 1.0: - xs:abstract - xs:attributeFormDefault - xs:base - xs:block - xs:blockDefault - xs:fixed - xs:mixed - xs:processContents Thanks, Alonza

dfdl:calendarLanguage - should allow an expression?
by Steve Hanson 29 May '13

29 May '13

DFDL has the design point that the combination of schema & data should give the same result regardless of locale and/or machine. To create a schema that does vary across locale or machine requires the user deliberately to use expressions for the relevant DFDL properties (encoding, decimal separator, etc) and parameterise the schema, using either built-in DFDL variables or user-defined variables. However the dfdl:calendarLanguage property is only defined as a String, I think it should also allow an expression as otherwise a schema is tied to a particular locale for it's calendar language support.

examples of decimal validation using pattern facet
by Mike Beckerle 24 May '13

24 May '13

Roger costello of Mitre provides this example of using pattern facet. Basically, it expresses several different possible formats, all of which are some combination of digits and a optional decimal point. In terms of cobol-style patterns it is one of these formats: 99 99.9 99.99 99.999 99.9999 I am not sure a textNumberPattern can handle the optionality of the decimal point. I know we can deal with the varying number of fraction digits, and the fixed number of integer digits, but conditional decimal point I am unsure about. ---------- Forwarded message ---------- From: Costello, Roger L. <costello(a)mitre.org> Date: Fri, May 17, 2013 at 4:00 PM Subject: RE: examples of decimal validation using pattern facet To: Mike Beckerle <mbeckerle.dfdl(a)gmail.com> Cc: "Cranford, Jonathan W." <jcranford(a)mitre.org> Hello Mike,**** ** ** **Ø **Can you send an example of the lat/lon validation **** **Ø **you mentioned on yesterday's Daffodil call?**** ** ** Here ya go:**** <xsd:simpleType name="foo"> <xsd:restriction base="xsd:decimal">**** <xsd:minInclusive value="00"/> <xsd:maxInclusive value="59.9999"/> <xsd:pattern value= "[0-9]{2}|[0-9]{2}\.[0-9]{1}|[0-9]{2}\.[0-9]{2}|[0-9]{2}\.[0-9]{3}|[0-9]{2}\.[0-9]{4}" /> </xsd:restriction> </xsd:simpleType>**** ** ** /Roger**** ** ** *From:* Mike Beckerle [mailto:mbeckerle.dfdl@gmail.com] *Sent:* Thursday, May 16, 2013 8:15 AM *To:* Costello, Roger L. *Subject:* examples of decimal validation using pattern facet**** ** ** Roger, Can you send an example of the lat/lon validation you mentioned on yesterday's Daffodil call? The other members of the workgroup are wondering what can't be done via totalDigits/fractionDigits, etc. The rationale for why pattern facet is not supported on numbers in DFDL is that we already have a much more powerful mechanism for parsing and unparsing numbers called textNumberPattern. The pattern facet only allows pass/fail using a regex, and is considered redundant (and problematic) for numbers as a result. ...mike -- Mike Beckerle | OGF DFDL Workgroup Co-Chair | Tresys Technology | www.tresys.com**** -- Mike Beckerle | OGF DFDL Workgroup Co-Chair | Tresys Technology | www.tresys.com
