Summary: I don’t have any major comments regarding the technical content of the draft. However, as seen in my comments below, I fail to see exactly how RFC 1738 is updated.

Major Issues: None

Minor Issues:

The Abstract text says:

   "This document specifies the "file" Uniform Resource Identifier (URI) scheme, replacing the definition in RFC 1738.”

Q1: I suggest that the text should say that the document “updates the file URI scheme defined in RFC 1738”.

Q2: Related to Q1, in RFC 1738 the “file” scheme is defined as a URL, but in the draft it is defined as a URI. What is the reason for that?

Q3: Related to Q1, it is unclear exactly what parts of the RFC 1738 scheme is updated. For example, is the syntax updated, is the usage scope updated etc? The second
       paragraph says something, but it is unclear whether it’s related to the actual update, or whether it just provides some information regarding the usage
       of the scheme. The Acknowledgements section says that the draft is “derived” from RFC 1739. What does “derived” mean? I think there should be clear and explicit text about exactly what is updated.

Q4: Related to Q3, the text says that things are backward compatible in “most situations”. I think a little more text is needed, and e.g., examples of non-backward compatibility.

Q5: I see that RFC 1738 is only a Informative Reference. Someone can correct me if I’m wrong, but doesn’t it have to be Normative since the draft is normatively (I assume) updating the RFC?

Editorial Issues: None
