Applications typically work like this: - Convert user's font request to a fontconfig pattern, - Apply fontconfig configuration on it using target="pattern", - Get a sorted list of fonts matching that pattern from fontconfig. The list is returned as a set of fontconfig patterns itself, - Choose the font to use (typically the first one having the requested character), - Apply fontconfig configuration on the font pattern using target="font". So, what it means is that for example if you want to turn off antialiasing on Bitstream Vera Sans for sizes less than 7.5, you should do that using target="font". If you do it with target="pattern", it will turn off aa for all fonts if the request is Bitstream Vera Sans, regardless of whether you have that font installed or not. If you want to write fallback rules such that DejaVu Sans be substituted for Bitstream Vera Sans, that's done with target="pattern", because you want to modify the request.
