--- Comment #4 from Akira TAGOH <akira at tagoh.org> ---
Okay, here is another proposal:
  http://cgit.freedesktop.org/~tagoh/fontconfig/commit/?h=bz59438-2

the test case in comment#1 in question would introduces the warning in this
case and no more make the empty match pattern:

$ FC_DEBUG=1028 ./fc-match/fc-match
...
Fontconfig warning: "/home/tagoh/.config/fontconfig/conf.d/000-bz59438.conf",
line 7: No <test> nor <edit> elements in <match>
...
        Loading config file
/home/tagoh/.config/fontconfig/conf.d/000-bz59438.conf
Add Subst match
        pattern any family Equal(ignore blanks) "sans-serif"
edit
        Edit family AppendLast "foo";
...

This doesn't prevent <alias> inside <match> exactly though.

Sure. but I suppose that feature isn't available in expat. it may be a good
opportunity to switch the default parser to libxml though, as we had Bug#34266
in bz, we need to polish a bit for libxml support perhaps. there seems some
distros enabling it by default, it's not used in Fedora. so I'm not sure how
better it works on. maybe I should try...
