It solves the "part of the font file has bogus blank glyphs"

What is already there is so verbose very few people use it, and when
they do use it they usually mix up things and it does not work the way
they expect it to work due to all the layers of verbosity that get in
the way of human parsing

I've never seen problems with simple succinct statements like :
        <alias>
                <family>serif</family>
                <prefer>
                        <family>Bitstream Vera Serif</family>
                        <family>DejaVu Serif</family>
                        <family>Times New Roman</family>
                        <family>Thorndale AMT</family>
                        <family>Luxi Serif</family>
                        <family>Nimbus Roman No9 L</family>
                        <family>Times</family>
                </prefer>
        </alias>

OTOH the match target/test is a reinvention of emacs' let's use lisp
syntax as configuration syntax hell

Another oververbose statement
