Currently Bamboo is offering Java and YAML Specs for the purpose of "configure by code".

There should be an additional option e.g. on the plan's configuration page under select button "Actions" to allow "Show plan as XML" which under the hood triggers a "View plan as Java Specs" action and a subsequent conversion of Java to XML.

Motivation for that can be:

• XML is easier to convert compared to Java and YAML, thus compatibility with other tools can be improved.
• For getting most Bamboo UI features, Java Specs is the better choice over YAML. Though for the sole purpose of configuring a build by code, learning Java is not the best option. However, XML is well known.
