I think it would help to elaborate a bit more on the intended meaning. Suggestion:

The subtag denotes a simplification of a root language. 

Simplification of language here refers to ways of controlling expressions in a language to make reading or comprehension easier for particular target audiences, such as children or adults with limited education, second-language learners, or people with cognitive disabilities. Examples of ways in which expressions are made simpler might include use of limited vocabulary, or avoidance of certain grammatical constructs.

This subtag represents a generic simplification of a language. For a given language, certain agencies or user communities may formulate rules for how to simplify expressions; this subtag does not distinguish any particular simplified language varieties. For many usage scenarios involving simplified forms of language, this generic subtag may suffice. Additional subtags may be registered to indicate specific varieties if necessary.
