-In this `other` document, the reference path item has a Security Requirement for the Security Scheme "MySecurity".  But there is a Security Scheme by that name in the `other` document as well.  As discussed in [Resolving Implicit Connections](#resolvingImplicitConnections), which "MySecurity" gets used is [implementation-defined](#undefinedAndImplementationDefinedBehavior).  However, as also documented in that section, it is RECOMMENDED that tools resolve component names from the [entry document](#documentStructure).  As with all implementation-defined behavior, it is important to check tool documentation to determine which behavior is supported.
+In the `other` document, the referenced path item has a Security Requirement for a Security Scheme, `MySecurity`. The same Security Scheme exists in the original entry document.
