W3C TAG feedback on draft-ietf-appsawg-file-scheme-03

<https://github.com/w3ctag/wiki/wiki/fileUrl>

Version under review:
https://tools.ietf.org/html/draft-ietf-appsawg-file-scheme-03

## General comments

There hasn’t been – to this point – a document that describes how the `file://` scheme works, and for that reason this is a good document. We are glad to see that the document specifies how to convert between file URIs and OS-dependent system filepaths.

### Limitations

Regarding the use of `file://` URIs on the web, there are a few issues that need to be resolved for interoperability:

1. How does `file://` fit into the web's origin model?
2. How does retrieval of `file://` URIs fit into
   [Fetch](https://fetch.spec.whatwg.org/) and/or the [URL standard](https://url.spec.whatwg.org)?

This document does not address any of these issues, so we encourage the APPSAWG to consider addressing these.

Regarding Fetch and URL, we recommend coordinating with Anne van Kesteren (@annevk) of the WHATWG.

The TAG would be happy to coordinate with APPSAWG to address the question of what the origin of `file://` is (coordinating with others like Anne as necessary).
