Agreed. Even that is incorrect, since there may not be a primary language
subtag, such as in the case of "x-duerst". So I'd recommend something more
like:

=>
In summary, a language tag is composed of one or more parts: typically a
primary language subtag followed optionally by a series of other subtags
such as script and region.
