using XML-based Earth Orientation Parameters in a zip file triggers an exception
When EOP data is parsed from an XML file, it works well as long as the file is in a regular directories hierarchy, but fails when the file is in a zip archive.
In this case, an exception is triggered while loading the data, as the global stream used to read the archive is automatically closed when the archive entry corresponding to the XML file is read. This prevents the analysis of the rest of the archive to be completed properly.
