Hi, I am using MODS to record metadata for video files. I keep getting an error that says, "This schema does not appear to be valid by itself ( as a part of another schema it might still be OK): Duplicated attribute type found!" when I try to open the MODS schema in XMLSPY. I am trying to register the schema with Oracle XDB, and it also gives me the same error. The duplicated type attribute that the error is referring to is found in the definition of the complex types "titleInfoType" , "nameType" and "relatedItemType". In these definitions the "type" attribute is defined as part of the MODS schema and also included as an attribute group reference to "xlink:simpleLink". Could anyone on this list please suggest a way to eliminate this error? Thank you, Prajakta Vaidya
