I think that the main problem is that you haven't got the correct URL
for the XMLSchema-instance namespace. It should be:

                       ^^^ no /10/

Then you need to sort out what the location of the schema that you're
pointing to is from the instance document. I think it's trans.xsd in
the same directory as the instance document.

Now, you aren't using a namespace for the elements in your document
(e.g. the transactions element) and from your previous post, your
schema doesn't have a target namespace, so you need to use the
xsi:noNamespaceSchemaLocation attribute, and its value needs to be the
(relative) URI pointing to the schema.

So the start tag of the transactions element in your instance document
should look like:

<transactions xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

*However* I don't think that this has anything to do with the XML
document not being transformed with the XSLT stylesheet. As far as I
can see, you haven't given IE any pointer to the XSLT stylesheet that
you want to use with the document. You need an xml-stylesheet
processing instruction at the top of your instance document, something

<?xml-stylesheet type="text/xsl" href="trans.xsl"?>
<transactions xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

That tells IE to use trans.xsl to transform the instance document.

Also, IE6 doesn't use MSXML4 unless you do the
validation/transformation using a script. If you're just loading in
the XML document, IE6 won't validate automatically against an XML
Schema schema (only against an XDR schema).

I hope that's some help,
