showtree.xsl - Exposing the node structure of an instance

This stylesheet showtree.xsl is useful for learning the node structure
created by an XSL engine for a given instance. It has been tested on XT
19990115 as matching the 19981216 working draft.

This stylesheet will report the node structure and content of an input
document, noting the ordinal positions in the hierarchy of each component
of the ancestry.

This stylesheet exposes root, element, attribute, text, comment, and pi nodes.

This stylesheet does not (cannot?) expose the namespace nodes (only other
kinds of node).

For example, given the XML instance: 

<?xml version="1.0"?>
<?pi1 value of pi1?>
<!--comment number 1-->
<greeting
  pub-id="+//ISBN 1-894049::CSL::Samples::SHOWTREE//Document SHOWTREE
Test//EN"
  attr2="Value of second attribute">
<purpose>To convey a greeting</purpose>
<test1>A test<test2>of depth<test3>to three levels</test3></test2></test1>
<!--comment number 2-->
<prelude id="start" xmlns:info="http://www.CraneSoftwrights.com/resources/";>
<?pi2 value of pi2?>
<info:detail>Information about Greeting</info:detail>
</prelude>
<value>Hello world!</value>

</greeting>

The resulting output is as follows (note that mailers may interfere with
the display of long lines below):
