# Class 2B — Dependent Privilege Descriptors Still Exist

## Shared meaning {#meaning}

The first two characters `2B` identify `Dependent Privilege Descriptors Still Exist`. A dependent privilege descriptor prevents the requested change. A class gives a directory-level family; each member still needs its own message, transaction aftermath, and response evidence.

## Members {#members}

The locked catalogue contains 2 members in this class:

[`2B000`](../../2b000/), [`2BP01`](../../2bp01/)

## Version boundary {#versions}

Member links lead to their own versioned facts; consult the version pages and source evidence for exact presence and change boundaries.

## Sources {#sources}

Members are generated from `data/classes.json` and the locked SQLSTATE directory.
