• https://github.com/buildingSMART/BCF-API/commit/0f3e26677589ad086a960baa786490fd235c5abe -> id and name properties ❌ -> We've discussed this and came to the conclusion that we don't port id properties separately to the XML exchange. Bringing several XML files to the same project, each having their own ids, would make combining those very complicated and you would have to maintain several external ids for the same properties. If they would not be maintained, then having the ids would not provide any benefit.
