I have a metadata file as below:<?xml version="1.0" encoding="UTF-8"?>

when I imported it with the following options: Import mode=File Upload; File type= Single File (XML,...); Import actions=No action on import; styleSheet=none; Validate=yes; Kind=Metadata; Group=Sample group; Datasets=Datasets
After I hit the "Insert" button, it return the following error message:SAXParseException : src-resolve: Cannot resolve the name 'xlink:simpleAttrs' to a(n) 'attribute group' component.
What may be wrong with it -- either this xml file misses any xlink attribute, or the schema is not correct? but which schema file to be updated, if a schema problem?
Any help on it is much appreciated. I am stuck on this for a while now.
Thank you so much.
