However, is this a known > limitation with Xerces? Xerces lazily assembles the Schema as it validates the document. It defers reading/processing a schema document for a given target namespace until triggered by a name {element, attribute or type} from that namespace. The namespace of the root element of your document differs from the target namespace of AIXM-ADR.xsd so this seemingly unrelated schema document is never read and no element declaration is found for "Update". If you change the schemaLocation attribute to xsi:schemaLocation="http://www.aixm.aero AIXM-GML-BasicMessageTypes.xsd http://www.aixm.aero/eur AIXM-ADR.xsd" it should work. > Any help would be appreciated. > > Regards, > > Scott > -- > View this message in context: http://www.nabble.com/import-of-root- > element-from-secondary-schema-tf2039564.html#a5612891 > Sent from the Xerces - J - Users forum at Nabble.com. > > > --------------------------------------------------------------------- > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] Michael Glavassevich XML Parser Development IBM Toronto Lab E-mail: [EMAIL PROTECTED] E-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
