In the XPath data model, namespaces are represented by namespace nodes, not
by attribute nodes. So you can't create them using xsl:attribute.

XSLT 2.0 has an instruction xsl:namespace for creating namespace nodes, but
there is no direct equivalent in XSLT 1.0. There's a workaround, which
involves creating a dummy element in the relevant namespace in a temporary
tree, and then copying its namespace nodes using xsl:copy-of.
