Hi Michele Please can you send the original spreadsheet ? I want to add another column to record the discussion on the WG call. Here is an example of where I do not think the relative path is correct. The discriminator expression should be {../Transfer_Frame_Version in [0]}. In infoset terms, Spacecraft_Id_V1 is a sibling of Transfer_Frame_Version. Also you said that you saw no need to implement DFDL assert - so what are the dmx:assertExpression attributes doing? <xs:complexType name="TypeMasterChId"> <xs:sequence> <xs:element name="Transfer_Frame_Version" type="xs:int" dfdl:lengthKind="explicit" dfdl:lengthUnits="bits" dfdl:length="2" dmx:representation="Integer16" dmx:assertExpression ="../Transfer_Frame_Version eq 1" dmx:assertMessage="Invalid TF version detected." dmx:assertPropagate="true"/> <xs:choice> <xs:element name="Spacecraft_Id_V1" type="xs:int" dfdl:lengthKind="explicit" dfdl:lengthUnits="bits" dfdl:length="10" dmx:representation="Integer32" > <xs:annotation> <xs:appinfo source=" http://www.ogf.org/dfdl/dfdl-1.0/"> <dfdl:discriminator test="{./Transfer_Frame_Version in [0]}" /> </xs:appinfo> </xs:annotation> </xs:element> <xs:element name="Spacecraft_Id_V2" type="xs:int" dfdl:lengthKind="explicit" dfdl:lengthUnits="bits" dfdl:length="8" dmx:representation="UInteger8" dmx:assertExpression ="../Spacecraft_Id_V2 in [82, 83, 84]" dmx:assertMessage="Invalid Spacecraft ID detected."> <xs:annotation> <xs:appinfo source=" http://www.ogf.org/dfdl/dfdl-1.0/"> <dfdl:discriminator test="{true}" /> </xs:appinfo> </xs:annotation> </xs:element> </xs:choice> </xs:sequence> </xs:complexType> Regards Steve Hanson IBM Integration Bus, Hursley, UK Architect, IBM DFDL Co-Chair, OGF DFDL Working Group smh@uk.ibm.com tel:+44-1962-815848 mob:+44-7717-378890 From: Steve Hanson/UK/IBM To: Michele Zundo <michele.zundo@esa.int> Cc: DFDL-WG <dfdl-wg@ogf.org>, Mike Beckerle <mbeckerle@tresys.com> Date: 17/02/2016 08:58 Subject: Re: OGF DFDL WG Call Agenda 2016-02-16 Thanks Michele, we will discuss on the next WG call.
