Some properties             are defined such that only an exact match makes sense, and             connection managers MUST NOT satisfy a request with a channel             where that property does not match; some properties are defined             such that the connection manager MAY treat the request as merely             a hint, and make a best-effort attempt to satisfy it. This is             documented separately for each property.&lt;/p&gt;            &lt;p&gt;If this dictionary contains a property whose semantics             are not known to the connection manager, this method MUST fail             without side-effects (in particular it must not create a new             channel).&lt;/p&gt;            &lt;tp:rationale&gt;             &lt;p&gt;This is necessary if we want to be able to invent properties               in future that, when used in a request, are hard requirements               rather than just hints. A connection manager that did not know               the semantics of those properties could incorrectly return a               new channel that did not satisfy the requirements.&lt;/p&gt;           &lt;/tp:rationale&gt;            &lt;p&gt;The connection manager MUST NOT respond successfully,             and SHOULD NOT create a new channel or cause any other             side-effects, unless it can create a new channel that satisfies             the client's requirements.&lt;/p&gt;            &lt;p&gt;Properties that will be set by this argument need not have write             access after the channel has been created - indeed, it is             expected that most will be read-only.&lt;/p&gt;</p></td>
