Expressions
<IF ONE_TO_MANY>
The relationship is a one-to-many relationship and a matching relationship is NOT defined in the opposite direction.
<IF ONE_TO_ONE>
The relationship is a one-to-one relationship and a matching relationship is NOT defined in the opposite direction.
<IF ONE_TO_MANY_TO_ONE>
The relationship is a one-to-many relationship and a matching relationship IS defined in the opposite direction.
<IF ONE_TO_ONE_TO_ONE>
The relationship is a one-to-one relationship and a matching relationship IS defined in the opposite direction.
<IF MANY_TO_ONE_TO_MANY>
The relationship is a many-to-one relationship and a matching relationship IS defined in the opposite direction.
<IF REQUIRES_MATCH> (deprecated)
关系要求匹配数据必须存在于关系所针对的文件中，这样本地字段中的数据才会被视为有效。默认情况下，所有关系默认要求“to”结构文件中的匹配数据，但这可以通过添加“RequiresMatch”来覆盖：HarmonyCoreRelations部分的关系的自定义条目错误。
<IF TO_MANY>

<IF TO_ONE>
The relationship targets a single record (i.e. it is a one-to-one, one-to-one-to-one or many-to-one relationship).
