Sigh.  Yes, it means an embedded comma; only the string name parser 
(FcNameParse) splits things at punctuation.  This is useful for '-' where
<string>sans-serif</string> means the sans-serif family and not the sans 
family at size 'serif'.

If you want to check for any of a list, you can have multiple values in the
<test> case:

	<test name="family" qual=any>

That will look for either 'times' or 'courier'.

Or, you can use:

	<test name="lang" qual=all>

to check for both en and de.

I'd prefer to not emit warnings for reasonable syntax; I'm not sure how
one would rewrite the values to avoid the warnings which seems pretty
