I get just one similar error in the log for every file I try to validate
with this schema.  Only the elements name changes.

Okay here we go...

You are right it isn't an lxml problem!  Sorry, but I had to start
somewhere.

Good idea here is the output from: http://www.xmlme.com/Validator.aspx

Validation Results:
Schema Error: System.Xml.Schema.XmlSchemaException: The targetNamespace
parameter '' should be the same value as the targetNamespace
'http://www.sifinfo.org/infrastructure/1.x' of the schema. at
System.Xml.Schema.BaseProcessor.SendValidationEvent(XmlSchemaException
e, XmlSeverityType severity) at
System.Xml.Schema.SchemaCollectionPreprocessor.Preprocess(XmlSchema
schema, String targetNamespace, Compositor compositor) at
System.Xml.Schema.SchemaCollectionPreprocessor.Execute(XmlSchema schema,
String targetNamespace, Boolean loadExternals, XmlSchemaCollection xsc)
at System.Xml.Schema.XmlSchema.CompileSchema(XmlSchemaCollection xsc,
XmlResolver resolver, SchemaInfo schemaInfo, String ns,
ValidationEventHandler validationEventHandler, XmlNameTable nameTable,
Boolean CompileContentModel) at
System.Xml.Schema.XmlSchemaCollection.Add(String ns, SchemaInfo
schemaInfo, XmlSchema schema, Boolean compile, XmlResolver resolver) at
System.Xml.Schema.XmlSchemaCollection.Add(String ns, XmlReader reader,
XmlResolver resolver) at
System.Xml.Schema.XmlSchemaCollection.Add(String ns, XmlReader reader)
at Validator.Button1_Click(Object sender, EventArgs e)

Okay, so it is me.  At this point, which mailing list should I be
bothering?  If you know how I can set the targetNamespace of my document
to match my schema, please email me but consider carefully if it is
appropriate to copy this list.

Thanks for all your help,
