In Part 2 of the series, we will further explore the new co-constraint features, specifically assertions and the conditional type assignment mechanism.
本系列的第2部分将进一步探讨新的共同约束功能，具体包括断言和条件类型分配机制。
The section element removes that constraint because anything within it is part of the section.
section元素取消了这种约束，因为其内部的任何内容都是节的一部分。
A common example is a co-occurrence constraint, where the constraint on one part of a document depends on another.
一个常见示例就是同现约束(co - occurrence constraints)，在这种情况中，文档某部分的约束取决于其他部分。
