I'm looking at creating xml files which use the schema defined in ODM1-2-0.xsd.

I downloaded the schema from the CDISC site, opened it in Stylus Studio and then did a validation which gave the following error:

Validating ODM1-2-0.xsd...
http://www.w3.org/2001/XMLSchema.dtd:121,9: warning: Attribute 'xmlns' has already been declared for element 'schema'
:0,0: Complex type '__AnonC1' violates the Unique Particle Attribution rule in its components 'Signature' and '##other'

The XML document ODM1-2-0.xsd is NOT valid (1 errors)

Can you tell me what this means?


CDISC Schema

Hi Simon,
the first warning is because the XML Signature schema starts with

<!DOCTYPE schema
PUBLIC "-//W3C//DTD XMLSchema 200102//EN" "http://www.w3.org/2001/XMLSchema.dtd"
<!ATTLIST schema
xmlns:ds CDATA #FIXED "http://www.w3.org/2000/09/xmldsig#">
<!ENTITY dsig 'http://www.w3.org/2000/09/xmldsig#'>
<!ENTITY % p ''>
<!ENTITY % s ''>

Inside XMLSchema.dtd there is this declaration

<!ATTLIST %schema;
targetNamespace %URIref; #IMPLIED
%nds; %URIref; #FIXED 'http://www.w3.org/2001/XMLSchema'

where %nds; is expanded into "xmlns" because the 's' entity in the internal DTD is set to an empty string. So the ATTLIST has two definitions for the xmlns attribute, hence the warning "Attribute 'xmlns' has already been declared for element 'schema'".

The other error is caused by this structure in the ODM1-2-0.xsd schema

<xs:element name="ODM">
<xs:element ref="Study" minOccurs="0" maxOccurs="unbounded"/>
<xs:element ref="AdminData" minOccurs="0" maxOccurs="unbounded"/>
<xs:element ref="ReferenceData" minOccurs="0" maxOccurs="unbounded"/>
<xs:element ref="ClinicalData" minOccurs="0" maxOccurs="unbounded"/>
<xs:element ref="Association" minOccurs="0" maxOccurs="unbounded"/>
<xs:element ref="ds:Signature" minOccurs="0" maxOccurs="unbounded"/>
<xs:any namespace="##other" minOccurs="0" maxOccurs="unbounded"/>

The final entry, <xs:any namespace="##other"> means "anything that is not part of the targetNamespace namespace can be placed here"; but the previous entry, <xs:element ref="ds:Signature"> is indeed allowing an element that is not part of the ODMG namespace. So there is ambiguity on which declaration should be used to validate what comes after the Association element.

Hi Alberto,

Thanks for your quick response.

So does this mean that the xsd downloaded from the CDISC site is invalid?

Can I edit it to make it valid and proceed from there or do you think that is a bad idea i.e. will that give me problems later on?

Hi Simon,
yes, I (and other persons - see http://www.cdisc.org/bbs/forums/thread-view.asp?tid=2324&posts=5&start=1) think that the CDISC 1.2.0 schema violates the UPA rule of XML Schema (Unique Particle Attribution); you could edit the schema to remove the xs:any element declaration, but this would break the extension mechanism of CDISC. A better approach should be switching to the 1.2.1 revision of the CDISC schema, where they changed the way extensibility is performed (removing the usage of xs:any). See http://www.cdisc.org/models/odm/v1.2.1/index.html
