[IPP] IPP Everywhere and "The Great Compromise"

As a random bystander I can confirm that "one of X and Y" sounds a bit odd.
Although the context does make it clear.

How about "Clients MUST support either DNS-SD or WS-Discovery or both" to
eliminate any final confusion with English's exclusive or.

While I'm being usless let me also suggest another wording "The
intersection between the set of client's supported protocols and the set
{DNS-SD, WS-Discovery} must not be the empty set."
