I don't like this, for at least two reasons:

1.  If the goal if to facilitate matching, then the direction of fallback 
ought to be from "yue" (or "cmn", etc.) back to "zh".  It doesn't make sense 
to put the fallback information in "zh" in that case.

2.  As Addison noted, we already have a precedent for using multiple fields 
to indicate multiple Prefix values.  I see no point in putting multiple 
values in a single "Encloses" field and introducing a new comma-separation 
convention for just this field.
