[xsl] Associate xml with no namespace to namespace of schema

[sudheshna iyer <sudheshnaiyer@xxxxxxxxx>]

I have a xsd with namespace. 

I need to validate an xml that is coming with no namespace?

How can I do that? xml spy doesn't allow this? Are there any attributes that I can use? I only can change xsd but not xml and I can't remove namespace in xsd. 

Tried to add the following attributes:
elementFormDefault="unqualified" 
attributeFormDefault="unqualified"

But doesn't work? Sorry that I am posting to xsl group, but somebody might have encountered this problem before.
