Rather than referring to RFC 1766, I would recommend to refer to RFC 3066 [1] instead, which was just published recently and it obsoletes RFC 1766. The main difference between RFC 1766 and RFC 3066 is that the latter allows three-letter language codes defined in ISO 639-2, in addition to two-letter language codes defined in ISO 639. As for XML, "2.12 Language Identification" of XML 1.0 Second Edition [2] notes: Note: [IETF RFC 1766] tags are constructed from two-letter language codes as defined by [ISO 639], from two-letter country codes as defined by [ISO 3166], or from language identifiers registered with the Internet Assigned Numbers Authority [IANA-LANGCODES]. It is expected that the successor to [IETF RFC 1766] will introduce three-letter language codes for languages not presently covered by [ISO 639]. and productions 33 through 38 have been removed to allow three-letter language codes. There are many languages which only have three-letter codes but don't have two-letter codes, so it would be unfortunate if `:lang' pseudo-class cannot be used for those languages while the `xml:lang' attribute allows them.
