RE: conditional namespaces

You've told the system what you want the local name and the namespace URI of
the attribute to be, but you haven't given any hints about what you want the
namespace prefix to be. So it has to make one up. Why do you imagine it
should choose "ns", of all possible names? If you want to influence the
prefix, write <xsl:attribute name="banana:{$attribute}"
namespace="{$namespace}">. Most processors will respect your wishes if they
can, though they aren't obliged to.
