Hi

There seems to be a discrepancy around the proper way to encode country coudes and their expected processing in XML Docbook and the XSL stylesheets. This matter already surfaced an year ago, but I got into trouble nevertheless, so I thought to bring this discussion up again. Please help me deal with it.

1) Docbook XML DTD does not declares the xml:lang attribute, so we must use lang. I wonder why. (It is not a namespace issue, since none is involved.)

2) lang should use ISO 3166 codes, that mandate the form "pt-BR", instead of "pt_BR" or "pt_br". Norm confirmed that in http://lists.oasis-open.org/archives/docbook/200107/msg00076.html.

3) The XSL stylesheets process my <article lang="pt-BR"> using the common/pt.xml file, which is not correct. "pt_BR" doesn't work either, only the value "pt_br" makes it behave correctly. Looks like the atribute value must match the filename exactly.

4) The language specification does not fuind its way into the HTML generated code. I thought it would be very nice if it did, so I tried to override some templates that generate it, but I would have to translate the wrong "pt_br" to the correct "pt-BR" to use it. Not very nice, since it should be correct already.

... any suggestions?
