Yes; more because XSLT doesn't consider namespace declarations
(xmlns:* attributes) to be attributes.

The only method of doing this at the moment is to add a dummy
attribute in the namespace that you want:

  <xsl:attribute name="myprefix:dummy"
                 namespace="{my dynamic namespace}" />

This will force the XSLT processor to add a namespace declaration for
the required namespace and with the required prefix.

The other thing that you might be able to do, if your source document
contains a namespace node for the namespace that you want to add, is
to copy the namespace node from the source to the result, with
something like:

  <xsl:copy-of select="namespace::myprefix" />

Cheers,

Jeni
