I have to deploy the approval workflow as explained in
https://docs.wso2.com/display/AM210/Managing+Workflow+Extensions
Currently we are working with 2.1.0, but in the near future, we will migrate to 2.2.0.
In version 2.1.0 to different alternatives are provided: Using EI or using BPS as shown in
https://docs.wso2.com/display/AM210/Adding+an+Application+Creation+Workflow
But I see that, in 2.2 version, only the BPS alternative is provided
https://docs.wso2.com/display/AM220/Adding+an+Application+Creation+Workflow
As far we understood, EI is the newest, and is a super-set of BPS. Why is the suggestion missed from 2.2?
