I appreciate such detailed feedback, thank you! Parsing of workbook.xml is implemented in the library itself in `parseWorksheetPaths` function I mentioned it briefly in the article, but decided to omit it as main focus was on Codable protocols.

I will definitely update the "s" attribute parsing to have a more sensible name. Will also link to the standard from the README file, although not sure that will help with a document of this size.
