I did something similar, to aggregate keywords for the keywords <meta> 
in the page <head>. The keywords are comma-separated texts, like
<%attr>
    keywords => 'personal site, gallery'
</%attr>

This code is in the root-level autohandler, and the result is a list of 
texts from all the components of the call-chain.

% my $comp = $m->request_comp;
% my %seen; my @kwds;
% while ( $comp ) {
%   push(@kwds, grep { ! $seen{$_}++ } split(/\s*,\s*/, 
$comp->attr_if_exists('keywords')) );
%   $comp = $comp->parent;
% }

--Pascal
