Most configurations are similar: oftentimes only the transport (TCP or UDP) and the discovery protocol are different. It would therefore be nice to configure the 2 default transports in separate files, and include them from other configurations.

This way, changes / optimizations to transports would not have to be copied to all configurations, but would be done only in a single file.

Example:

  <include
        file="${transport-config:tcp-default.xml}"
  />  
   <MPING />
   ...

This includes tcp-default as transport in a configuration. Note that if system property transport-config was set, this would allow for dynamic inclusion of different transports.

See how this works in practice, and possibly add more functionality, e.g. (inspired by Infinispan)

• Add protocols at a given location
• Remove a protocol
• Add/remove/replace attributes
