[oXygen-user] Oxygen with XSL schema or DTD

Having Oxygen "know" the XSLT elements and attributes is great. Is it possible to attach the Apache unofficial XSL sxhema [http://svn.apache.org/viewvc/xmlgraphics/fop/trunk/src/foschema/fop.xsd?view...] to Oxygen so that users of XSL-FO have the same benefits as XSLT users? Or is there other means for achieving that? Thanks, Mark
