[Zope] [Q] Book problems with early examples

[Carl David]

I wrote concerning book examples, and was asked to clarify what was going
on.
Here is "navigation" which exists in root:
<dtml-if expr="_.len(PARENTS) > 1">
<h2><dtml-var title_or_id>Section</h2>
<a href="..">Return to parent</a><br>
</dtml-if>


<ul>
<dtml-in expr="objectValues('Folder')">
<li><a href="&dtml-absolute_url;">

<dtml-var title_or_id></a>
<br></li></dtml-in>
</ul>
and here is index_html from /ChemAdm/FallSched:
<dtml-var standard_html_header>
<h1>This is the Fall Master Schedule</h1>
<hr>Choose  from the above days of the
week to
see<hr>
<dtml-tree>
<dtml-var getId>
</dtml-tree>
<hr>
<p>This is the <dtml-var id> Document in the FallSched folder.</p>
<dtml-var standard_html_footer>


To the best of my knowledge there are no typos here, and yet ...
Thanks for any help
