Sorry for the confusion. My application does not deal with the Java implementation of any of the schema types. It uses the information from the schema to determine test cases to generate and then uses the XMLBeans API (mainly XmlCursor) to create an XML instance. Once the instance is complete I then validate it via the XmlObject.validate(XmlOptions options) method and save the object to a file.
One of the first things I do is to compile the schema XSD (with XmlBeans.compileXsd(...)) to get a SchemaTypeSystem object. This provides me with everything else I need. The schema defines several abstract types, each of which has some number of other schema types that extend them (i.e. <xs:extension base="myPrefix:AbstractBaseType">). As the program works its way through a document type to identify and generate test cases, when it encounters an element defined by an abstract type, it scans the schema for any types that extend that type. It then generates the element with the type reference attribute to point to the specific concrete schema type. I also generate the child content that is defined by the specific concrete type. The generation logic inserts the namespace(s) as attributes of the root element. I insert the "default" namespace (i.e. xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance") and the schema-specific namespace (e.g. xmlns:myPrefix="my-schema-site") ["myPrefix" and "my-schema-site" are not the actual values used, of course]. As I mentioned, if I validate this using the XMLBeans command line validator, there is no complaint, but when I used the API validator, I get the error shown. Regarding your comment on the schema version that is used, what can I do about that? I insert the "standard" XML heading into the file before validating and saving. E.g. <?xml version="1.0" encoding="utf-8"?> Does the version number here indicate the schema version number? -- View this message in context: http://xmlbeans.996285.n3.nabble.com/Validation-issues-tp7520p7523.html Sent from the XMLBeans User mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@xmlbeans.apache.org For additional commands, e-mail: user-h...@xmlbeans.apache.org
