# General

This document summarizes the compatibility between the s1kd-tools and
each issue of the S1000D specification for which support is planned.

  - \[empty\]  
    Support is planned but not yet implemented.

  - X  
    Support is implemented.

  - /  
    Support is partially implemented.

  - \~  
    Support is not planned. Usually this is because older issues of the
    specification did not cover the function of the tool.

<div class="note">

Although a tool may not directly support an issue of S1000D, it may
still be possible to use with that issue.

For example, the s1kd-brexcheck tool is said not to support Issue 2.0 or
Issue 2.1, because the BREX data module schema was not introduced until
Issue 2.2. However, an Issue 2.2 or greater BREX data module can still
be used to check Issue 2.0 or Issue 2.1 CSDB objects.
