In effect you *are* using the result-ns attribute ... you are telling the
XSL engine to interpret the result node tree using the syntax conventions
of the namespace with the empty prefix ... the engine then checks to see
what that prefix is, but it only knows which prefix to use by way of the
result-ns attribute.  As Chris mentioned, the result-ns attribute is the
mechanism by which you are communicating to the engine the semantics of the
result.  If you don't have to ask the XSL engine to do anything special,
there is no need to use the attribute.

All that is needed is to identify the XSL instructions:

  <xsl:stylesheet xmlns:xsl="http://www.w3.org/TR/WD-xsl";>

>I take it that only HTML4 and XSLwd are understood.

Perhaps more accurately stated as only HTML4 and XML syntax conventions are
used by the engine when emitting the result node tree as a file.  Other
engines may offer off-the-shelf support of other syntax conventions for
representing the result node tree.

Consider the declaration:

<xsl:stylesheet
       xmlns:xsl="http://www.w3.org/TR/WD-xsl";
       xmlns:fo="http://www.w3.org/TR/WD-xsl/FO";
       result-ns="fo">

Here the stylesheet writer is telling the XSL engine through the result-ns
attribute that the result node tree is to be interpreted as a hierarchy of
formatting objects ... the engine isn't required to emit the tree as a file.

I hope this helps.
