Don,

Some comments:

1. In the example, under “username” it is suggested that “punycode” (i.e. xn--abc123) is acceptable. IMO, this is wrong. I’m almost sure the protocol doesn’t require this.

2. Same thing for second-level and top-level domains. We should not encourage software to display the A-label to end users. A-label is for the wire. Users should see only the U-label. After all , UA is about processing and displaying domain names in a proper manner.

3. EAI is about Unicode, so not sure why the “ASCII or Unicode” bullet points. This can be interpreted that ASCII-only email addresses are EAI too.

4. Since we are mentioning the idea of an authoritative list of TLDs, we should point the reader where to find one.

My two quick cents,

Dennis
