/ Elliotte Rusty Harold <elharo@metalab.unc.edu> was heard to say:
| The finding says:
|
| Natural Language. The xml:lang attribute is not treated specially in
| the Infoset but is intended to have a scoped effect much like the base
| URI. This intention is made explicit in this specification.
|
| I'm assume you're aware that the XInclude group is in the process of
| creating a new language property for the element information item. How
| does this affect the finding?

I haven't thought carefully about that yet.

| "Languages are compared case insensitively."
|
| Using what language? Case mappings are not always the same from
| language to language. I is not the uppercase form of i in Turkish, for
| example. xml:lang values are normally ASCII but don't have to be.
| What's probably intended here is that languages are compared case
| insensitively within the ASCII range using English case mappings.

Uhm, yes that should be made clearer. The content of xml:lang is
supposed to be IETF RFC 3066 language tags, which are only US ASCII, I
believe.

| 2.6 Unexpanded Entity Reference Information Items
|
| Should system identifiers that differ only in case of the protocol and
| or the the authority be considered unequal? What about system
| identifiers that use percent escapes?
|
| Same question for Document Type Declaration Information Items and
| UNparsed entity information items.

I think the easy answer is, performe Unicode code-point comparison.

                                        Be seeing you,
                                          norm
