Yes -- it can also go into per-group or per-page customizations.

Something like that *can* work, but better would probably be
to simply do:
If you want it to happen for every page, then you can set
(again, in local/config.php):
$GroupHeaderFmt = '(:include Site.Keywords:)(:nl:)' . $GroupHeaderFmt;
which means that the contents of Site.Keywords would be
included on every page. See the FAQ question at the bottom
of http://www.pmwiki.org/wiki/PmWiki/GroupHeaders for the details.

$HTMLHeaderFmt *is* an array syntax. :-) It means to add
a value to the end of the array.

$HTMLHeaderFmt is a way to add things to the output using PHP
statements (i.e., from within a script), while page directives
are a way to do things from within wiki markup. So, $HTMLHeaderFmt
is normaly aimed at script writers and wiki administrators, while
the page directives are intended for authors who probably don't
have a way to modify the scripts. The markup rules for the
page directives convert the markup into the appropriate
Of course, an administrator can choose whichever approach best
suits his/her needs. :-)
