I would not go for this method for various implementation reasons...

Thanks, I thought of this and would be my second choice, because the array 
created from this would not create $HTMLHeaderFmt['myrecipe'] (associative) 
but $HTMLHeaderFmt[<num>] (normal array).

I am thinking of using this:
$temp['styles'] = $HTMLHeaderFmt['styles'];
$temp['infobox'] = "<link rel=.../>";
$HTMLHeaderFmt = array_merge($temp, $HTMLHeaderFmt);
This seems to work.
I hoped if pmwiki calls the user defined styles to be loaded at the 
end of execution? The idea of having local.css is for overriding syles called 
before.

I am only concerned that this does not cause any issues with multiple recipes 
setting their entries in $HTMLHeaderFmt.
