/**
 * <p>
 * Strategy interface for resolving values from an operation definition.
 * </p>
 * <p>
 * {@link Patch} implementation generically defines a patch without being tied to any particular patch specification.
 * But it's important to know the patch format when resolving the value of an operation, as the value format will likely
 * be tied to the patch specification. For example, the <code>value</code> attribute of a JSON Patch operation will
 * contain a JSON object. A different patch specification may define values in some non-JSON format.
 * </p>
 * <p>
 * This interface allows for pluggable evaluation of values, allowing {@link Patch} to remain independent of any
 * specific patch representation.
