I have just added 'globalValues'. You could now do something like :

try:
    site_title
except NameError:
    site_title = globalValues['site_title']
else:
    globalValues['site_title'] = site_title

Which is perhaps a little ugly. :-)

The better way of achieving this is to provide uservalues in your site
config file. These are already available to every page.

I thought I suggested (I should have done) :

    sections['section name']['pages'][pageIndex]['namespace']

or :

    for section in sections.values():
       for page in section['pages']:
          namespace = page['namespace']

This only gives you access to pages in the current directory though.,
and index pages of the directories below.

You can't access the restindex or uservalues of pages through indextree.

Every page in indextree has a 'link-title'. If this hasn't been
explicitly set in the restindex of a page, it defaults to the page title.

What other values do you need access to ?
