Symbolic links, in XML terms, would be elements from some other tree
inserted by reference.  XML doesn't do that, and if it did do that,
there'd be a case for some kind of "is it really there, or referenced?"
distinction.  (Attributes, by file system analogy, would be things like
mtime and ctime.)

What you were describing, if I'm remembering it right, is wanting a
result tree that was just like your source tree only without the
attribute nodes.

<xsl:template match="node()">
    <xsl:copy>
        <xsl:apply-templates select="node()"/>
    </xsl:copy>
</xsl:template>

does that; it's not recursive, it's a single template.  It'll get
applied to all the nodes, but that's the magic of the XSLT declarative
model.
