Dear Gordon,
I hope what I say here is correct (not my field of expertise but I
thought I knew this one).

The namespaces is a good guess, and that is how I read it being
documented at
http://xml.apache.org/xerces2-j/properties.html
('same as schemaLocation attribute in *instance documents*').

I think the error is that you are using setProperty while all you want
to do is have Xerces find the imported files.

The problem is that you load the schema based on
XMLInputSource is = new
org.apache.xerces.xni.parser.XMLInputSource(null,null,null,(Reader)r,
null);
So you only specify a Reader, which is basically a stream of characters.
So Xerces has no idea where to find schema's that are imported relative
to any file, because there is no reference to the file. So you can
remove the setProperty, and simply tell Xerces where to find related
files by making that part of the inputsource, e.g.
XMLInputSource is = new
org.apache.xerces.xni.parser.XMLInputSource(
null,
"file:///c:/projects/schemaProc/flat/thisfile.xsd",
"file:///c:/projects/schemaProc/flat/",
(Reader)r,
null);
(untested, but this should give you the idea).

Ah, or maybe this won't work at all. Any reason why you do not specify
the file location as "./CSICommon.xsd" in your schema?
If you have schema-locations in your schema file which do not point to
actual existing file-names, you should specify an entity resolver which
maps CSICommon to an inputstream of the file CSICommon.xsd.
Kind regards,
--Sander.
