I figured it was something like that. It's also kind of ironic that the more people become involved in the refinement of documents like this the less and less obvious their contributions become. For example, old official hand-written documents were delegated to scribes. Then authors in this era sent their work out to type-setters who used hand crafted tools created by another layer of artisans. Then to printing presses full of machines which were designed by artisans, built by artisans, and operated by artisans. Now in modern times the layers are as deep as the technology sector, with thousands of people having contributed to digital publishing equipment and thousands of programmers writing and re-writing better and better software to create a better and better product. It's interesting seeing generations of compounded human knowledge side by side with earlier generations.
