Hello, The XML documents I work with have the following form: <?xml version="1.0"?> <!DOCTYPE dmodule [ <!ENTITY TBD SYSTEM "http://myserver.mydomain.net:81/svn/s1000d/ TBD.svg" NDATA SVG> ]> <dmodule ...> ... <graphic boardno="TBD"/> ... </dmodule> As you can see, the figures system location are in a subversion repository and when specified as in the sample, figures are displayed OK in Author mode, CSS associated to the documents have the following entry to handle figures: graphic { display: block; content: url(unparsed-entity-uri(attr(boardno))); } I was trying to separate XML content from the actual subversion repository server inserting in the catalog.xml for my document type association: ... <rewriteSystem systemIdStartString="http://s1000d/" rewritePrefix="http://myserver.mydomain.net:81/svn/s1000d/ "/> <rewriteURI uriStartString="file://" rewritePrefix="http://myserver.mydomain.net:81/svn/s1000d/ "/> ... and changing the ENTITY declaration to: <!ENTITY TBD SYSTEM "http://s1000d/TBD.svg" NDATA SVG> But when in Author mode, the figure is not displayed, the following error message is displayed in a red box instead of the image: "Cannot display image http://s1000d/TBD.svg" It seems the rewrite statement in catalog.xml is not working. Any ideas? Regards, Jose M. Mangas
