Two ideas:
When you say you put it on 'the root', do you mean the literal result
element which is to be the root of the output document, or the
xsl:stylesheet element?  (If you are using 'literal result element as
stylesheet' these are the same so ignore this bit).  Its usual to put
exclude-result-prefixes on the xsl:stylesheet - I don't think it
should make a difference, but you might try it.

My second guess is that you are using xsl:copy or xsl:copy-of.  The
problem is that these copy all the namespace nodes present.  Remember
you get a namespace node on an element for all namespaces declared on
that element *or* any of its ancestors: they do not just appear where
the actual declaration is.  There are two ways round this that I know
of:
  a) move the namespace declarations in the stylesheet or source
document so they do not appear on the nodes you are copying (not
always possible or practical)
  b) use xsl:element instead of xsl:copy (messy but it works) or
xsl:copy-of (even messier).

Or just live with it ;-)
