Technically it never says so, but I think it's clear enough for people
reading between the lines.  Thanks.

Here are some other passages with the issue Julian mentioned:

§8.1 Run-time shared libraries:
	"For example, the libgdbm3 package should install libgdbm.so.3.0.0
	 as /usr/lib/libgdbm.so.3.0.0."

	"For example, the libgdbm3 package should include a symbolic link
	 from /usr/lib/libgdbm.so.3 to libgdbm.so.3.0.0."

§8.4 Development files:
	"For example, the libgdbm-dev package should include a symlink from
	 /usr/lib/libgdbm.so to libgdbm.so.3.0.0."

§8.6.2 How to use dpkg-shlibdeps and the shlibs files:
	"If your package contains only compiled binaries and libraries (but
	 no scripts), you can use a command such as:

	     dpkg-shlibdeps debian/tmp/usr/bin/* debian/tmp/usr/sbin/* \
	       debian/tmp/usr/lib/*"

§12.6 Examples
	"Architecture-specific example files should be installed in a
	 directory /usr/lib/package/examples with symbolic links to them
	 from /usr/share/doc/package/examples, or the latter directory
	 itself may be a symbolic link to the former."
