Hmm. If you would have a template to match foreach-elements, and you
apply-templates without selecting any node in particular, then the processor
should do all the rest for you, pushing the descendant::foreach --no matter
what depth - through its matching template and treat it the same way as the
higher level foreach...

So, by adding this
<xsl:template match="foreach">
  <xsl:apply-templates select="do" />
</xsl:template>

the do-template in my example, with a slightly modified variable (otherwise
it suffers the same defects as pointed out by David and Wendell --text will
not be selected) will ensure that the descending foreach's have a matching
template that is of higher priority than the node() template.

So, make the variable
<xsl:variable name="vdo" select="node()" />

If the do element (or in your altered design: the descendant nodes of the
foreach) contain(s) nested foreach elements, this template will treat
*their* descendants (the do, or, if you will, 'body' of the foreach) as they
are encountered, and will use the other already defined templates to provide
you with the correct result.

So the answer to this one would be: no.
