Re: Identity transformation (without using xsl:copy)

A few weeks ago I posted a message (below) asking how to do an identity
transformation (without using <xsl:copy>) on instance documents that
contain namespace declarations.  The resounding response was "no way".
[Thanks for your input!]  Okay, after much testing and reading I have
convinced myself that you are correct - <xsl:copy> must be used.  It
seems to me that this puts some serious limits on XSLT.  Consider this
simple problem:  write a stylesheet which does an identity
transformation, but where all element (local) names are converted to
upper case.  For example:

If this is the start document:

<?xml version="1.0"?>
<j:juicers xmlns:j="http://www.juicers.org">
     <j:juicer id="omega">
         <name xmlns="http://www.names.org">
             Mighty Omega Juicer
         </name>
     </j:juicer>
</j:juicers>

Then this should be the result document:

<?xml version="1.0"?>
<j:JUICERS xmlns:j="http://www.juicers.org">
     <j:JUICER id="omega">
         <NAME xmlns="http://www.names.org">
             Mighty Omega Juicer
         </NAME>
     </j:JUICER>
</j:JUICERS>

If I could use <xsl:element> then I could easily accomplish this
transformation.  However, it escapes me how to do it if I am forced to
use <xsl:copy>.  

The more general question is: if I use <xsl:copy> to copy over an input
tree to an output tree how can I make modifications to elements names
(such as converting the local part to upper case, as shown above), and
modifications to each element's (non-namespace declaration) attributes?
