So, the CFR should be supported as yet another format of fontconfig's config
file, and still the application programmer should not expect as if the CFR
does not simplify the requirement of the consideration of multiple fonts
for a face name? If so, some translator from the CFR file to a file in fontconfig
DTD would be the solution?
