Parse Result namespace Source Map does not account for multiple files

[zdne]

In the prism of solving apiaryio/api-blueprint#8 the source map should be not only be capable of holding the location within a file but also be able to identify the file.

This is currently not the case and should we need it in a future the Source Map element would have to be changed in a backward incompatible way.

@zdne This makes sense to me.

RFC0006 made sure the current source map refract is future-proof for adding multiple file support.

I don't think we should close this since we didn't add multiple file support yet. We just made the existing structure future proof.

[smizell]

Wish granted :)

[pksunkara]

@smizell Should we move this to api-elements repo?

[smizell]

Move to API Elements.
