The FLUID-5903 features of the IoC testing framework explained at https://github.com/amb26/infusion-docs/blob/FLUID-5903/src/documents/IoCTestingFramework.md#using-sequencegrade-to-build-up-complex-reusable-test-sequences introduced a member named "elements" holding a hash of names to sequence definitions. It's quite likely that this will become a reserved word in a future version of the framework, as per the discussion in https://wiki.fluidproject.org/display/fluid/Plan+to+Abolish+Invokers+and+Events . We should quickly take the opportunity to rename this "sequenceElements" as also being more descriptive.
