Xsd lets you explicitly specify if you are dealing with one or more elements, no need to encode that information in the data itself. It also gives you access to concrete number types, so you don't have to rely on the implementation to actually support values like 1 and 2.

Not every XML has associated XSD. You need to transfer XSD. You need to write code generator for that XSD or otherwise use it. A lot of work which is unnecessary when you can just write `JSON.parse(string)`.
