I agree entirely with Syd!
Part of the semantics of "placeName" is that it should contain a *name*.
If you wanted to make a placename index from a text, you wouldn't want
it to include strings like "his home".
Note that you can use the @type attribute on <rs> to indicate that the
referring string in question refers to a place (rather than, say, a person)
Note also that you can have placenames *inside* referring strings, as
one of my favourite examples in chapter ND shows:
spending some time in our <rs key="NY1" type="place">modern
<name key="BA1" type="place">Babylon</name>
</rs>, <name key="NY1" type="place">New York</name>, I have proceeded to
the <rs key="PH1" type="place">City of Brotherly Love</rs>.
