ISO 2022 and ISO TR 9573 describe methods of charset shifting
for use in SGML. The TEI has developed an approach, too.
And SGML Open (the consortium of vendors) has a committee on
the issue.

For the Docbook DTD we've decided that to handle element-level
charset shifts we need CHARSET, LANG, and COUNTRY common attributes.
But shifting between charsets at arbitrary points is more
complicated, and we've been waiting for SGML Open to indicate
the manner in which vendors are willing to support it, so haven't
implemented anything.
