I've run across this problem that I saw Yuichi ask about, and you answer [2]: [1] http://lists.w3.org/Archives/Public/xmlschema-dev/2000Aug/0017.html [2] http://lists.w3.org/Archives/Public/xmlschema-dev/2000Aug/0018.html >If you have the instance document: > > <A> > <B/> > </A> > >there is an ambiguity as to whether B matches the first or the third line >of the content model for A. Therefore, the content model itself is >nondeterministic, as reported by XSV. However, Yuichi's example had two defintitions for the element B, in mine I use an ANY: ><complexType name="SignatureMethodType" mixed="true"> > <!-- (0,unbounded) elements from (1,1) external namespace --> > <sequence minOccurs="0" maxOccurs="1"> > <element name="HMACOutputLength" minOccurs="0" > type="ds:HMACOutputLengthType"/> > <any namespace="##any" minOccurs="0" maxOccurs="unbounded"/> > </sequence> > <attribute name="Algorithm" type="uriReference" use="required"/> ></complexType> > ><simpleType name="HMACOutputLengthType"> > <restriction base="integer"/> ></simpleType> and get ><schemaError char='15' line='55' phase='instance' >resource='file:/I:/2web/WWW/Si >gnature/Drafts/xmldsig-core/xmldsig-core-schema.xsd'>non-deterministic >content m >odel for type SignatureMethodType: {Wildcard: >##any}/{http://www.w3.org/2000/09/ >xmldsig#}:HMACOutputLength</schemaError> ></xsv> for ><Signature Id="MyFirstSignature" xmlns="http://www.w3.org/2000/09/xmldsig#"> > <SignedInfo> > <CanonicalizationMethod > Algorithm="http://www.w3.org/TR/2000/WD-xml-c14n-20000710"> > </CanonicalizationMethod> > <SignatureMethod > Algorithm="http://www.w3.org/2000/09/xmldsig#dsa"> > </SignatureMethod> > <Reference URI="http://www.w3.org/TR/xml-stylesheet/"> ... What would the problem here be? Also, I guess it's true to say a schema can have errors that will not be addressed upon validation, but only upon validation of its instances? __ Joseph Reagle Jr. W3C Policy Analyst mailto:reagle@w3.org IETF/W3C XML-Signature Co-Chair http://www.w3.org/People/Reagle/
