Since the publication of the new IANA Language Subtag Registry as the place to find language subtags, rather than the ISO code lists, this question is no longer relevant.
The article was almost completely rewritten to explain this.
The Portuguese translation has been removed, since the text is now so radically different.
The IETF has just published a new specification describing how to construct language tags. The new RFC 4646, which replaces RFC 3066, with the new IANA Language Subtag Registry address a number of long standing issues with language subtags.
This article has been completely rewritten to provide a gentle introduction to how to construct language tags following the new rules.
