可姑且将what he called看作插入语

有一读者问： 有这样一个句子：

Karl Liewellyn developed what he called the law-government continuum to illustrate the point that legal systems can be constructed in an infinite number of ways.

请分析整句话的句子成分。

全句的基本结构是“主语（Karl Liewellyn)+谓语(developed)+宾语(what he called the law-government continuum)”。what he called the law-government continuum是一宾语从句，由缩合连接代词what （=that which）所引导。为方便起见，亦可将what he called看作插入语。to illustrate...of ways是一不定式短语，用作目的状语。如作内部分析，that legal systems...of ways是一同位语从句（与其前的the point同位）。
