As per the font-conf manual, using <accept> for an alias means appending the acceptable families after the matching <family>. An example:
<alias binding="same">
<family>Menlo</family>
<accept>
<family>Liberation Mono</family>
</accept>
</alias>
The above would allow, for example, to have Menlo used if present. Liberation Mono would only be used if Menlo is missing.
However, that doesn't work on Chromium, where prefer seems to be required to have the alias working at all:
<alias binding="same">
<family>Menlo</family>
<prefer>
<family>Liberation Mono</family>
</prefer>
</alias>
But this means the original Menlo will never be used, even if present.
