Yes, I can understand that :
<match target="pattern">
<test qual="any" name="family">
<string>mono</string>
</test>
<edit name="family" mode="assign">
<string>monospace</string>
</edit>
</match>
means
« For a font which got the string mono in its family metadata field
(qual="any" is not defined but I'd guess any means as global as you can)
assign the string monospace as the family field »
And this is only by reading the xml tags (pattern with test + associated
action), without going into the schema or anywhere else. Of course you
need to know beforehand fonts declare metadata, which include "family".
In your example I have to guess the second field is a pattern, the third
is the substitution, it does not permit changing one field based on
another, you've used space as separator which will bite you later, etc
etc.

Except configuration files need to be readable and explicit tags are way
better than magic "//" expressions for this (or implicit arguments based
on ordering)
