[oXygen-user] Support for jar: URNs?

Hi Eliot,

If the catalog file is located directly on the local drive, relative 
references to it are interpreted as having the same protocol (which is 
the "file" protocol). I consider this to be correct.
I understand that you would like relative references like this: 
"test.zip!/catalog.xml" to be expanded to absolute URLs having the 
protocol something like "zip:file" but this is not quite easy or correct 
to accomplish and would require some patches to the Xerces catalog resolver.

What I tested and could be used as a workaround:
Have the catalog file located directly inside the zip (or jar).
For example in the catalogs list I referenced it like this:

> zip:file:/D:/projects/eXml/samples/dita/flowers/concepts/test.zip!/catalog.xml

and it contained a relative reference like this:

>  <uri
>         name="http://test/res/plugin/dita4publishers/net.sourceforge.dita4publishers.common.xslt/xsl/lib/relpath_util.xsl"
>         uri="personal.xsl"/>

which got solved also inside the same zip.
