To anybody who can help. I am trying to convert from DTD to XML schema and having this problem: In DTD I had a bunch of attributes defined this way: --------------------------------------------------------------------------- <!ENTITY % X_NAME "Length CDATA #FIXED '70' Truncate CDATA #FIXED 'Allowed' "> <!ENTITY % X_ZONECODE "Length CDATA #FIXED '8' Case CDATA #FIXED 'Upper' "> ----------------------------------------------------------------------------- That was defined in a separate module and then in dtd module itself it's been used like this: <!ELEMENT %Zn_cd; (#PCDATA )> <!ATTLIST %Zn_cd; %X_ZONECODE; > <!ELEMENT %Zn_Desc; (#PCDATA )> <!ATTLIST %Zn_Desc; %X_NAME; > As a result of it I can reuse attribute groups defined by X_ names and, what is even more important, #FIXED allowed me not to specify these attributes in XML instance file - they've been taken from DTD. In XML schema I am trying to do a similar thing: --------------------------------------------------------------------------------------- <xsd:attributeGroup name = "X_ZONECODE"> <xsd:attribute name = "Length" use="fixed" value="8" type = "xsd:string"/> <xsd:attribute name = "Case" use = "fixed" value = "Upper" type = "xsd:string"/> </xsd:attributeGroup> <xsd:attributeGroup name = "X_NAME"> <xsd:attribute name = "Length" use = "fixed" value = "70" type = "xsd:string"/> <xsd:attribute name = "Truncate" use = "fixed" value = "Allowed" type = "xsd:string"/> </xsd:attributeGroup> <xsd:complexType name = "ZoneType"> <xsd:sequence> <xsd:element name = "ZoneCode"> <xsd:complexType> <xsd:simpleContent> <xsd:extension base = "xsd:string"> <xsd:attributeGroup ref = "X_ZONECODE"/> </xsd:extension> </xsd:simpleContent> </xsd:complexType> </xsd:element> <xsd:element name = "ZoneDescription"> <xsd:complexType> <xsd:simpleContent> <xsd:extension base = "xsd:string"> <xsd:attributeGroup ref = "X_NAME"/> </xsd:extension> </xsd:simpleContent> </xsd:complexType> </xsd:element> </xsd:sequence> </xsd:complexType> --------------------------------------------------------------------------------------- Everything is fine but I have to specify attributes in XML instance file and my intention is to get them picled up from schema definition automatically. Anybody knows what I am doing wrong? My e-mail Michael_Fishman@i2.com. Thanks
