there are two answers to this: "yes" and "no".

According to the spec, you _never_ get any control over th eprefixes
used, and it is perfectly OK for an XSLT serialiser to always use
prefixes like kmsqzzxss1: kmsqzzxss2: .... even if the stylesheet uses
fo: or whatever.  (So this is the no, it can't be done answer)

However most (all?) systems do in fact try to preserve the namespace
prefixes in most situtaions. What they do when the result tree has
namespace nodes giving different prefixes to the same namespace
is a bit variable, and because of the answer above, the spec isn't much
help. But the answer is to make sure that the result tree does _not_
have such repeated namespace nodes. In the example in this thread the
stylesheet declares the test namespace on "" and t: all it has to do is
make sure that none of the t namespace nodes get copied to the output.
One way to do that is to use xsl:element rather than literal result
elements as the latter copy all namespace nodes in scope.
