Peter was using *.jar by way of casual example, not precept.  In fact,
since jar is based on zip, it is unsuitable for this sort of work (the
whole file has to be read before any can be processed).  A streaming
protocol similar to tar or cpio is the only reasonable alternative for
packaging, since an application can start working with the contents
before the whole archive has been downloaded.

Note also that packaging does not concern only XML entities -- there's
also the problem of bundling non-XML entities, such as vector and
raster graphics, audio and video clips, VRML worlds, etc., that are
referenced from within an XML document.

In the end, then, this is a problem that we have to solve anyway.

All the best,
