I was just checking Apache logs for the past month on our web server and noticed that the highest bandwidth was coming from downloads of RELAX NG schemas that we store there. When creating and editing XML files with oXygen, we typically use shared HTTP locations for our schemas. A little bit of testing shows that when opening and editing an XML file, an RNG schema is fetched over the network many times, not just when it is first opened. It seems to fetch it when the file is first opened, then when content is first added (in order to determine the valid elements and attributes), and then other times later during the editing. Is there any way to configure oXygen so that a schema file is downloaded once during an editing session and used from cache after that?
