Just being curious, but is there any meaningful relationship between what was labelled as SOURCE_NONE in the previous step and what this step calls "technical fields"? Things like "upstream" (which is not affected by the contents of the object, but is affected by the ref in question) and "if" (which merely exists to construct the language syntax) would fall into quite different category, so one might be subset/superset of the other, but I am wondering if we can take advantage of more table-driven approach taken by the previous step.
