Hi Thilanka,

While going through the AMQP spec [1] I too could not find much details
about it but found out the following under the topic " 3.1.3.3 The Topic
Exchange Type" it says, "The routing key used for a topic exchange MUST
consist of zero or more words delimited by dots. Each word may contain the
letters A-Z and a-z and digits 0-9".

Regards,
