Helvetica28L;56L;84L;112L;140L;168L;196L;224L;252L;280L;308L;336L;I have a fairly complex schema (2937 lines, 822 elements, 617 complexTypes) that xsv is reporting a schema error on: <non-deterministic content model for type Metad ataType: {http://www.sas.com/SASOMI}:CubeRegion/{http://www.sas.com/SASOMI}:Cube Region< What does this mean? FWIW, xsv does eventually properly evaluate the instance and detect the one known irregularity in the content. (shown below). It just takes it 12 HOURS on my 400Mhz PIII ! The actual instance is very small (26 lines). I suspect most of this time is in digesting the schema. It is very complex and has some circular types of element associations ( element A can optionally contain a B, and B can optionally contain an A). Is this why it takes so long? FWIW, Oracle's validating parser dies the death of a NullPointer when trying to process this schema: Exception in thread "main" java.lang.NullPointerException at oracle.xml.parser.schema.XSDBuilder.parseComplexTypeContent(XSDBuilde r.java, Compiled Code) at oracle.xml.parser.schema.XSDBuilder.parseComplexType(XSDBuilder.java, Compiled Code) at oracle.xml.parser.schema.XSDBuilder.parseTopLevelElem(XSDBuilder.java , Compiled Code) at oracle.xml.parser.schema.XSDBuilder.buildSchema(XSDBuilder.java:367) at oracle.xml.parser.schema.XSDBuilder.build(XSDBuilder.java:223) at oracle.xml.parser.schema.XSDBuilder.build(XSDBuilder.java:206) at XSDSetSchema.main(XSDSetSchema.java:24) XMLSpy can process this instance and schema and DOES NOT detect the obvious error that XSV eventually reports. It says the schema and instance are just fine. > <element > {http://www.sas.com/SAS > OMI}:Owner not allowed here in element {http://www.sas.com/SASOMI}:WTable: > < > < > < > < > < > < > < > < > < > < > < > < > < > < > < > < > < > < > < > < > < > < > < > < > < > < > < > < > < > < > < > < > < > < > < > < > < > < > < > < > << > <undeclared element > {http://www.sas.com/SAS > OMI}:Owner< Geneva28L;56L;84L;112L;140L;168L;196L;224L;252L;280L;308L;336L;------------------------------------------------------------------------ Michael Burns email: 0000,0000,FFFFMichael.Burns@sas.com Principal Systems Developer home: 0000,0000,FFFFmburns@bga.com Metadata Integration Technology voice: (512)258-5171x3264 SAS Institute, Inc. fax: (512)258-3906 11920 Wilson Parke Ave. www: 0000,0000,FFFFhttp://www.realtime.net/~mburns Austin, TX 78726-4052 sww: 0000,0000,FFFFhttp://sww.sas.com/~sasmkb "choose for yourselves today whom you will serve;... but as for me and my house, we will serve the Lord."
