Solution 1:

As @Rupe said, it sounds like you have fixated on one meaning of the word corresponding. When in most cases today the word corresponds denotes a relationship between two things. See MW dictionary for the exact definition of how it's being used in your documentation:

2: directly related to something

In the US you rarely hear correspond used to denote a type of communication, and when I do hear it it's often by the news to talk about their "(foreign, technical, political) correspondent".

Appropriate, however tends to denote 'rightness' or 'correctness', see MW dictionary:

1: right or suited for some purpose or situation

So it can be used to denote a relationship, but in a broader sense then corresponding.
