> There has been a lot of internal JPL work on flushing out new ideas with the workflow manager. One of those new ideas is to explicitly support differentiating between different types of {code}org.apache.oodt.cas.workflow.WorkflowTask{code} entities, classifying them as *sequential* (their current form) versus *parallel* (those that deal explcitly with branch and bound). Even though the current workflow system can support these activities, they are largely code-based and require modification and intrinsic knowledge of the Workflow event system.
> It would be nice to simplify this for the users and allow task.xml, conditions.xml and *.workflow.xml files (or explicit WorkflowRepos) to support this nomenclature. 
> I'll attach a proposed spec of what the updated XML files would look like using this paradigm. Then my goal is to take the existing workflow system and augment it with this functionality.
