Unfortunately my problem is that I did want to use a "copy-of" so that the
nodes being referred to
by the <ref> tag are actually "stitched" into the tree.
I tried to use the following but it doesn't seem to do the job. Note the use of
"copy-of" and
"ancestor::define".
Any pointers?
Thanks,
Anupam.

I see you're using 2.0, it's best to say explictly if you want a 2.0

I don't think you need to keep copying nodes and build copies of the
tree, you want to recursively walk over the existing tree not copy
branches of it:
<x>
<define name="DEF1">
<reg name="REG1"/>
</define>
<define name="DEF2">
<reg name="REG2"/>
<ref name="DEF1"/>
</define>
<block name="block1">
<reg name="REG3"/>
<ref name="DEF2"/>
</block>
</x>
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:key name="r" match="define" use="@name"/>
<xsl:template match="x">
<xsl:apply-templates select="block"/>
</xsl:template>
<xsl:template match="reg">
Register: <xsl:value-of select="@name"/>
</xsl:template>
<xsl:template match="ref">
<xsl:apply-templates select="key('r',@name)"/>
</xsl:template>
</xsl:stylesheet>
