I have a schema, which uses an imported namespace, and elements represented in that namespace are not recognized. What am I doing wrong? Thanks in advance.

Code: Select all

BTW the error reported by Oxygen is:

Code: Select all


E [Xerces] src-resolve.4.2: Error resolving component 'marcxml:controlfield'. It was detected that 'marcxml:controlfield' is in namespace 'http://www.loc.gov/standards/marcxml/schema/MARC21slim.xsd', but components from this namespace are not referenceable from schema document 'file:/myfile.xsd'. If this is the incorrect namespace, perhaps the prefix of 'marcxml:controlfield' needs to be changed. If this is the correct namespace, then an appropriate 'import' tag should be added to 'file:/myfilehybrid.xsd'.
