I think the IRI -> URI algorithm should not change (expect for the bit 
about normalization discussed previously).

What should be added is HRef -> IRI (whch implies that in some cases, 
that mapping would need to map query parameters to plain ASCII).

LEIRIs then could become a special case of the thing described above.

Repeating what I suggested on www-tag a few days ago 
(<http://lists.w3.org/Archives/Public/www-tag/2009May/0083.html>)...:

This has been under discussion for something like nine months. I think
the issues, as documented by Ian, Henri and now by Dan are
well-understood (and thanks for posting examples and test cases).

I think when we discussed this last October, Larry and several others
(including myself...) pointed out that the additional complexity as
compared to IRIs (RFC3987) can easily be layered *above* IRI, mapping
HTML5-references to IRIs by just by stating:

1) non-IRI characters found in the query part are encoded using the
document's character encoding, then percent-escaped (*)

2) all other non-IRI characters (such as space) are encoded using UTF-8,
then percent-escaped

Or, if we use LEIRIs as foundation instead
(<http://tools.ietf.org/html/draft-duerst-iri-bis-04#section-7>), we end
up with a *single* rule:

1') non-IRI characters found in the query part are encoded using the
document's character set, then percent-escaped (*)

Why does it need to be *more* complex than that?
