What functionality does the foo-data package loose if you purge foo?
Does "less /usr/share/foo/textfile" or "qiv /usr/share/foo/image"
suddenly stop working?

On the other hand, what functionality does foo loose if foo-data is

You can't have both depending on the other without causing a depends
loop, which is bad and easily causes install/purge failures. Think
about which dependency ensures a working binary to the user and which
only means the installation makes sense.
