How does HTTP get into this discussion?

I think that requirement comes from the wish to be able parse and 
resolve references that are invalid.

One way to do that is to simply point people to RFC 3986 (regexp-based 
extraction plus the resolution mechanism) and be done. We also could 
work on 
<http://greenbytes.de/tech/webdav/draft-reschke-ref-parsing-latest.html>, or 
integrate it into something else.

Alternatively, we could expand the ABNF to more or less match 
"everything", so doing what IRIbis does for LEIRIs, just doing a bit more.

I don't think it makes a huge difference.

As Björn observed, this only affects handling of invalid URIs/IRIs, so 
it's ok to write down rules for these *if* the UA vendors actually agree 
on the rules (my recollection is that they do not).
