Hi, I'm not sure if this is the right list to write my issue. But as long as it associates with developing I thought public-rif-dev would be appropriate. Have anyone tried to generate java classes from RIF-PRD xml schema [1]? When I try to do it I fail with the unique particle attribution rule [2] violated. Here is what xjc (the JAXB binding compiler) says to me: ----- > \>xjc .\PRD.xsd -d . > parsing a schema... > [ERROR] cos-nonambig: "http://www.w3.org/2007/rif#":Const and " > http://www.w3.org/2007/rif#":Const (or elements from their substitution > group) violate "Unique Particle Attribution". During validation against > this schema, ambiguity would be created for those two particles. > line 567 of file:/D:/(...)/PRD.xsd > Failed to parse a schema. ---- My solution to that is changing Retract element definition. In original schema we have (lines 567-578): <xs:complexType> <xs:choice> <xs:element ref="Atom"/> <xs:element ref="Frame"/> <xs:group ref="TERM"/> <xs:sequence> <xs:group ref="TERM"/> <xs:group ref="TERM"/> </xs:sequence> </xs:choice> <xs:attribute name="ordered" type="xs:string" fixed="yes"/> </xs:complexType> My proposition of changing schema: <xs:complexType> <xs:choice> <xs:element ref="Atom"/> <xs:element ref="Frame"/> <xs:group ref="TERM" minOccurs="1" maxOccurs="2"/> </xs:choice> <xs:attribute name="ordered" type="xs:string" fixed="yes"/> </xs:complexType> Second version works fine and I think means the same. What do you think? Does the fix look good for you?
