Comment 11 for bug 1034928

Conclusion from Fedora bug, Akira TAGOH said(https://bugzilla.redhat.com/show_bug.cgi?id=837520#c0):

> Still no changes in the behavior in the latest version of fontconfig,
> but it now warns when <test> contains multiple values or <alias> contains
> multiple <family>s. this is because the behavior isn't intuitive and
> doesn't work as expected necessarily. So you better consider to fix it
> to make clearer what you want to do with it.
>
> For solution, if you are expecting OR operator with that rule, add more
> <match>s or <alias>es. if you are expecting AND operator with that rule,
> just add more <test>s in that <match>.
