Property used to specify the timeout within clients when waiting for a response from the server.
Currently used within version 0x01 and 0x02 of the protocol, however this property may be unsupported in future protocol
versions when update message exchanges are added.
A comma separated list of protocol versions to be excluded from the list of supported versions.
Server side this property causes the specified versions to be removed from the list of advertised versions and will also
prevent selection of the mechanism if selected despite not being offered.
Client side this property will cause the specified mechanisms to be removed from the list of mechanisms supported by the
client, if the server offers the excluded mechanism the client will not select it.
If the value is specified as both a System property and within the environment map then both will be combined, care
should be taken to avoid excluding all mechanisms.
The System property is read on initialisation so should not be used to attempt real time updates to the list of supported
versions.
