I have a client that wants us to advertise an IP block assigned by another

There is nothing wrong with both of your originating the prefix, as long as the owner gives you permission. Plus it saves an ASN. If the link between you & the customer dies, things get far more interesting, but that doesn't mean you can't or shouldn't do it.

Of course, you can probably still find documentation against it. (You can find documentation for or against just about anything.)
