Mark,
A IPv6 only host has to have access to a IPv4 address to talk to IPv4 only hosts. The simplest way to do this is to actually stay dual stack and use DS-lite.
... the simplest (and recommended) way to do this is to use dual stack (full stop). DS-Lite is needed in some situations, primarily if you want to enable a v6-only ISP network and want to share one IPv4 address among multiple subscribers. But regular dual stack works very well, too, and is often deployed in the NATted-IPv4 and routed IPv6 configuration.
