The IPv6 Node Requirements is intended to document the minimal requirements for an IPv6 node, and a DNS resolver is not one of those requirements. You can have a perfectly-compliant IPv6 node that doesn't include any DNS support.
If we start down the road of saying:
"A node MUST include a DNS resolver if it needs to resolve DNS names."
wouldn't this lead to:
"A node MUST include SIP if it wants to use the Session Initiation Protocol", etc.?

Agreed. But how can a node find an address without MUST DNS. The point is that a requirement to use is based on the situation. My point last night.
