The caller specifies their preferred languages using the Accept-Language

Of course not. If the caller indicated that they want spanish, the CPL 
language-switch can do something specific in that case.

Right. If the accept-language looks like:

Accept-Language: en;q=1.0, es;q=0.0, de;q=0.5

the es language would be ignored for purposes of the CPL switch.
