I know that relative clause compounds are generally made with the following format.

sentence/verb/adjective + noun

My Genki I textbook supports this with the following example of a relative clause compound, with the noun 学生 being italicized in English.

あそこで本をよんでいる学生はみちこさんです。

The student who is reading a book over there is Michiko.

However I remember browsing Japanesestackexchange last year and finding some users referring to the noun part of a relative clause compound as a 'main clause'. This has recently made me question where the noun/'main clause' ends in Japanese sentences.

Edit: In other words, using the above example once more; is the entirety of 学生はみちこさんです the main clause which the relative clause modifies, or is it only the noun that is being modified; thereby restarting the sentence after the noun?

I'm asking as in the word doc for a book I'm translating I have two different examples of relative clause compounds, and I'm wondering which example is correct.

Example 1: 返事をした女の子がこちらに近づき、僕の手にナイフを[握]{にぎ}らせる。

Relative Clause: 返事をした

Main Clause: 女の子がこちらに近づき

Example 2: 荒野を渡る風よりもなお、アインの声は冷たかった。

Relative Clause: 渡る

Main Clause/noun: 風

However I remember browsing Japanesestackexchange last year and finding some users referring to the noun part of a relative clause compound as a 'main clause'. This has recently made me question where the noun/'main clause' ends (therefore the end of the total relative clause construct) in Japanese sentences.
