Very good question.  Indeed it would...  Here's the code if anyone
cares to suggest a solution:

$MarkupExpr['section'] = 'MkExpExtSection($args[0], $args[1])';
function MkExpExtSection($data, $template) {
  $template = ReadPage($template);
  $template = $template['text'];
  $data = ReadPage($data);
  $sections = explode("[[#ID", $data['text']);
  unset($sections[0]);
  foreach ($sections as $i => $section) {
    $sectionarray = '';
    $lines = explode("\n", $section);
    $id = substr($line[0], 0, strpos($line[0], "]]"));
    $sectionarray['id'] = $id;
    foreach ($lines as $line) {
      if (strpos($line, ": ") !== false) {
        $f = substr($line, 0, strpos($line, ": "));
        $v = substr($line, strpos($line, ": ") + 2);
        $sectionarray[$f] = $v;
        }
      }
    $out[$i] = preg_replace('/\\{\\$\\$(\\w+)\\}/e',
'ZAPfieldreplace("$1", $sectionarray)', $template);
    }
  return implode("", $out);
  }

One simple solution would be to require double colons or some other
variation in the data page...  Or some kind of leading symbol, or an =
sign.  Open to suggestions...

time:: I don't know yet
place:: my place
people:: just some friends
