This is something for an IDE, not for the compiler itself.
An IDE is free to store it's sources as it wants.

Parsing XML adds a lot of processing overhead, so should not be
supported in the compiler. What is more, most relevant
command-line options can be specified with directives, so you don't
really need the 'extra' info in the compiler sources.

But if you want to add such an extension to the IDE, please do.
