You think right. See p.23 of

About as useful as ro-FR, and less probable...

Please use "ca". I know that Catalan is as much "Spanish" as Castilian is.
But the guys that designed ISO 639 decided otherwise (and this is probably
more mnemonic for many people, many of them native speaker of "es"). So it
had to be this way.

This is completely frivolous.

Spelled Castilian in English.
Looks like Philippe is mixing Baleares with Canary here...

Sorry to contradict you slightly, John. Please note that this issue is
sensitive for some Catalans here in Spain, so I mention it for the sake of
everybody here knowing it.

Where is it spelled?

Particularly when I read
   Tags constructed wholly from the codes that are assigned
   interpretations by this chapter do not need to be registered with
   IANA before use.
inside clause 2, which otherwise says that the 2nd subtag when 2 letter
designates a country, and also says that 3rd and next subtags do not have
semantical restrictions.

Yes it is. Spain (as well as other countries) does have two levels of
administrative regions encoded in ISO/IEC 3166-2, recognising the dual
structure of its regional systems, with at the same time 17 autonomous
regions as well as 50 (or 52) provinces. When the limits are the same, there
is no distinction in codes. When they the autonomia is larger, case of
Canary Islands which is made of 2 provinces, designers of 3166-2 invented a
2-letter code from the English name of the autonomous region, that means
nothing and is not used here in Spain, but serves to designates it.

So yes, ES-CI does exist, and indeed designates the Canary Islands.
