Disable namespace prefixes in Transformer

Question

hi
I am stuck in a cyclic problem. JAXP XSLT and SchemaValidator do not work together. (Java 1.5 and 1.6)
I have a XSD with a namespace.
When I generate the XML using an XSLT I specify namespace using the namespace attribute of xsl:element
The JAXP transformer always generate the namespace prefix and equate the prefix with the actual URI
Is there a way to disable this behavior, that is, I do want the xmlns URI in the root element but not the prefix?
There are two reasons for wanting an XML without prefixes:
1) The Schema Validator provided with JRE is not able to validate the message with prefix, but it works fine with xmlns URI
<rootelem xmlns="urn:xmlns:xyz.abc.com"> validates fine
but
<ns0:rootelem xmlns:ns0="urn:xmlns:xyz.abc.com"> fails validation with error:
org.xml.sax.SAXParseException: cvc-elt.1: Cannot find the declaration of element 'ns0:rootelem'.
I am able to generate the first case when I use Saxon based OrangeXSLT plugin for Eclipse but JAXP based transformer always generate the second case.
2) More importantly, I have XML consumers that could use parsing without namespace support and prefixed element will not work there.
I am using StreamResult in the Transformer.transform() call and my guess is that the internal implementation of Transformer might be using a SAX ContentHandler (XML Serializer) to write XML to the outputStream and I guess one way to get around could be that I write a custom ContentHandler and use a SAXResult in the transform call. I am not sure if I am thinking in the right direction.
If I am correct in my guess, could someone please point to some implementation of XMLSerializer that could be overridden just to disable namespace prefixing behavior?
I have removed the namespace from the XSD for things to work. I would appreciate any help with this.

Moving to latest Xalan and Xerces solved the problem.
But a new one surfaced.
Xalan's latest transformer does not handle StreamSource correctly and throws some exception internally (IOException related to end of stream), with the message:
SystemId Unknown; Line #-1; Column #-1; Premature end of file.
It work correctly if a DOMSource is provided as the input. This does not make sense, since the InputStream my code is using for StreamSource is ByteArrayInputStream for an in-memory XML and such error would happen if this stream is read more than once without calling a reset in between.
Please let me know if this seems like a valid bug or if I am doing something wrong.
