	// Requests is a list of the one or more requests in this claim which
	// must co-satisfy this constraint. If a request is fulfilled by
	// multiple devices, then all of the devices must satisfy the
	// constraint. If this is not specified, this constraint applies to all
	// requests in this claim.
	//
	// References to subrequests must include the name of the main request
	// and may include the subrequest using the format <main request>[/<subrequest>]. If just
	// the main request is given, the constraint applies to all subrequests.

	// MatchAttribute requires that all devices in question have this
	// attribute and that its type and value are the same across those
	// devices.
	//
	// For example, if you specified "dra.example.com/numa" (a hypothetical example!),
	// then only devices in the same NUMA node will be chosen. A device which
	// does not have that attribute will not be chosen. All devices should
	// use a value of the same type for this attribute because that is part of
	// its specification, but if one device doesn't, then it also will not be
	// chosen.
	//
	// When the DRAListTypeAttributes feature gate is enabled, comparison uses
	// set semantics(i.e., element order and duplicates are ignored): list-valued attributes
	// match when the intersection across all devices is non-empty.
	// Scalar values are treated as singleton sets for backward compatibility.
	//
	// Must include the domain qualifier.

	// attribute and that its type and value are unique across those devices.
	//
	// When the DRAListTypeAttributes feature gate is enabled, comparison uses
	// set semantics (i.e., element order and duplicates are ignored):
	// list-valued attributes must be pairwise disjoint across devices.
	// Scalar values are treated as singleton sets for backward compatibility.
	//
	// This acts as the inverse of MatchAttribute.
	//
	// This constraint is used to avoid allocating multiple requests to the same device
	// by ensuring attribute-level differentiation.
	//
	// This is useful for scenarios where resource requests must be fulfilled by separate physical devices.
	// For example, a container requests two network interfaces that must be allocated from two different physical NICs.
