Re: xsl and schemas - getting rid of the xsi namespace

When you copy an element with xsl:copy of xsl:copy-of, it copies the
element itself and all the namespace nodes on that element. You're
copying a doc element with an namespace node for the
XMLSchema-instance namespace, so you get a namespace declaration in
the result. To avoid it, don't copy the element, instead use
xsl:element to create it; add the following template to your
stylesheet:

<xsl:template match="*" priority="-0.4">
  <xsl:element name="{name()}" namespace="{namespace-uri()}">
    <xsl:apply-templates select="node()|@*" />
  </xsl:element>
</xsl:template>

[The priority ensures that it's a higher priority than the identity
template you're currently using, and lower than the other templates
that you might have.]

Cheers,

Jeni
