schemaLocation attribute dropped after XSL transformation

[John]

I have an input document that contains a large base64 encoded
document. This document also declares a schema location in the root
element. I want to write an XSL stylesheet that makes an exact copy
(including the namespace and schema location) of the input document
except that it removes the base64 encoding and replaces it with the
text 'REMOVED'.

I have a stylesheet that does just that except that it drops the
schemaLocation attribute. Where that attribute is supposed to be I
get a ="" which then gives me an error when I parse the result because
it is not well formed XML.

I am using Xalan (not sure of the version) on Solaris with Java 1.3.1
on SunOS 5.8

Can anyone please tell me what I am doing wrong?

Thanks much,
-John

I don't see you are doing anything wrong. Here is what I got running your
document and stylesheet through Saxon 7.5.2:

<?xml version="1.0" encoding="UTF-8"?>
<abcocumentInfo xmlns:abc="http://abc.com/schema"
xsi:schemaLocation="http://abc.com/schema abc.xsd "
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

<BunchOfElements>....</BunchOfElements>

<Attachment Encoding="BASE64" FileType="PDF"
xmlns:abc="http://www.abc.com/schema">REMOVED</Attachment>
</abcocumentInfo>

I assume this is pretty much what you expected.
