A more thorough explanation:

A restrictive title is a specific name given to a statute or legal document that narrowly identifies the particular subject matter addressed by the legislature. This is in contrast to a general title, which broadly and comprehensively identifies the subject matter addressed by the legislature.

For example, Title VII of the Civil Rights Act of 1964 is a restrictive title because it specifically addresses employment discrimination and harassment on the basis of race, sex, pregnancy, religion, and national origin. In contrast, a general title might be something like "Civil Rights and Protections Act," which could cover a wide range of topics.

The purpose of a restrictive title is to make it clear to readers what the statute or legal document is about, so they can easily find the information they need. It also helps to prevent confusion and ensure that the document is interpreted correctly.
