This is a general theory question, but how is XInclude manifested? I understand the theory, but I have two questions about the implementation of it.
First, I assume there are "XInclude processors"? Just like XML has parsers, I assume there is something with processes XML files for XInclude references -- inflating the references with the actual XML? How is this accomplished in .Net?
Second, how does the (as yet mythical) XInclude processor resolve the files? The examples I've seen all have HREFs to other files, but what if your remote document is in a CMS somewhere, or is otherwise NOT on the file system? Do different processors have different methods of resolving XInclude references? Can you write your own resolvers for specific circumstances?
