SDK for processing WDCML files
This project is mostly of historical/archeological interest at this point. Before learn.microsoft.com (was: docs.microsoft.com) (whose content source is authored in markdown files, and versioned in Source Depot), there was MSDN (whose content souce was authored in a dialect of XML called WDCML, and versioned in git). This project is an SDK that you can use to perform automated/mechanical changes and transformations to WDCML. For example, you might have wanted to insert a paragraph of boilerplate at the top of every topic in a certain project declaring that the API were pre-release. Or generated hundreds of pages of reference content around API sets and UWP device families virtually for free.
This code became sadly obsolete when we moved from WDCML to (the grossly inferior) markdown. Thus we lost the WDCML SDK, and the ENORMOUS amount of value that it provided. IMHO, we should have stuck with WDCML, and a healthy writing team, and a healthy content engineering team, and steered clear of so-called "AI" (which is second-hand thought at best, and simply incorrect at worst). That way we would have maintained high quality and productivity as writers, in collaboration with the product team SMEs and their excellent and indispensable raw materials (such as specs, blog posts, etc.).
