As Jeni pointed out, you can generate a namespace declaration in the output
document by generating a dummy attribute that uses that namespace.
Fortunately your target document is a stylesheet, and stylesheets allow
dummy attributes to appear on any xsl element provided they are
namespace-qualified. (But don't put it on a literal result element!).

There's no way currently of generating a free-standing namespace declaration
in the output document, though if the processor implements the errata to
XSLT 1.0 then you can copy a namespace node from any source document using
<xsl:copy>.
