I noticed that too.

I lifted the DTML syntax for the tree from the ZBook tutorial. Here's my
DTML:

<SPAN CLASS=tree>
  <!--#tree particle branches_expr="objectValues(['Folder', 'DTML
Document'])" sort=id-->
    <!--#if expr="meta_type == 'Folder'"-->
      <!--#if tree-item-expanded-->
        <IMG SRC="<!--#var SCRIPT_NAME-->/HelpSys/hs_obook" ALIGN="TOP"
BORDER="0" width=16 height=16>
      <!--#else-->
        <IMG SRC="<!--#var SCRIPT_NAME-->/HelpSys/hs_cbook" ALIGN="TOP"
BORDER="0" width=16 height=16>
      <!--#/if-->
      <!--#var title_or_id-->
    <!--#else-->
      <IMG SRC="<!--#var SCRIPT_NAME-->/HelpSys/hs_dnode" ALIGN="TOP"
BORDER="0" width=16 height=16>
      <A HREF="<!--#var "particle.absolute_url()"-->/
         <!--#var tree-item-url-->?
         <!--#if tree-s-->tree-s=<!--#var tree-s--><!--#/if-->
         <!--#if tree-e-->&tree-e=<!--#var tree-e--><!--#/if-->
         <!--#if tree-c-->&tree-c=<!--#var tree-c--><!--#/if-->">
      <!--#var title_or_id--></a>
    <!--#/if-->
  <!--#/tree-->
</SPAN>

I don't see any extra whitespace in there. BTW, I haven't figured out the
purpose of <!--var SCRIPT_NAME>. To what does that refer?

Thanks for hints. I'll keep looking.
