Hi Chris!

I've read the maillist rules. Thank you for pointing that! Sometimes
it's not easy to overcome the habits.

Indexmenu plugin uses the simple construction, the same as
parserutils.php:620:p_get_first_heading():

if ($conf['useheading'] && $title_tmp=p_get_metadata($page,'title'))
$title=$title_tmp;

I have removed all "*.meta" files from data/ directory. After the
refresh I looked into newly created .meta file: 'title' is not there.

I noticed, that Doku_Renderer_metadata:73:header() is never called.  I
am using the following plugin as a extension for build-in headers:

http://wiki.jalakai.co.uk/dokuwiki/doku.php/tutorials/header

As I understand, if plugin overrides some build-in functionality, the
rendrer's header() is never called? Basically, I need to check in
plugin:header

if (metadata is being rendered)
{
        if (!$this->meta['title']) $this->meta['title'] = $text;
        if ($this->capture && ($level > 1)) $this->doc .= DOKU_LF.$text.DOKU_LF;
}

What is the best way to do so? Check if instance of $renderer is
Doku_Renderer_metadata class?

I am not sure what $this->capture means. Maybe "dump text for indexing"?

Thanks for your help!
