Hi Jens,

You are right, the W3C schema should be used. We will update the 
xlink.xsd schema from the XLink framework (the 
[Oxygen-folder]/frameworks/xlink folder) to the latest version from the 
W3C website.


Regards,
Sorin

The mapping is done by the default XML catalog which is enabled in Preferences -> XML -> XML Catalog. For fixing the error please replace the file [Oxygen-install-folder]/frameworks/xlink/xlink.xsd with the attached file which you can download from:
