Rules governing formation of adjectival and genitive modifications for Noun-Phrase


The following was observed in sawa's answer to "[Can ごとに be replaced by それぞれ
in this question?](https://japanese.stackexchange.com/a/5963/542)":

> ◯ 正月はそれぞれの家が門松を立てる。
>
> × 木村さんはそれぞれの会う人に挨拶している。
>
> ◯ 木村さんは会う人それぞれに挨拶している。

それぞれの会う人 is said to be an ungrammatical construction because it is modified
from outside of the relative clause. What are the rules for modifying noun-
phrases?

I had perceived それぞれの会う人 as a XのY construction i.e. I perceived 会う人 as a noun-
equivalent. Does this imply that a relative clause construction cannot act in
all ways that a noun can?

Also, are the following constructions valid?

  * [な-adjective] + [noun-phrase from relative clause construction]

  * [い-adjective] + [noun-phrase from relative clause construction]




A relative clause construction cannot act in all ways that a noun can.
Adjectival modification, genitive noun phrase, and relative clause are all
different things, and behave differently syntactically.

Assuming that a relative clause attaches to a noun phrase and creates a noun
phrase, whose categorical status is the same, is correct.

The problem is with adjectival modification and genitive phrases. There is a
need to distinguish between a noun and a noun phrase for them.
