The [Global Class Index](https://specifications.openehr.org/releases/AA_GLOBAL/latest/index.html) contains a link to the interface `I_TASK_PLAN_DEFINITION` which doesn’t exist in the HTML page of the [Task Planning Specification](https://specifications.openehr.org/releases/PROC/latest/task_planning.html#_i_task_plan_definition_interface).
Here is the ADOC file for this interface:
[specifications-PROC/docs/UML/classes/i\_task\_plan\_definition.adoc](https://github.com/openEHR/specifications-PROC/blob/8d34bed7568e3d2bc1e07d2db2c3bed9f998e5a0/docs/UML/classes/i_task_plan_definition.adoc)
(Including a function called “etc” which looks like a placeholder to me.)
The include was removed with this commit:
>
The interface is used in the return type of [`I_WORK_PLAN_DEFINITION#plan`](https://specifications.openehr.org/releases/PROC/latest/task_planning.html#_i_work_plan_definition_interface). Is this work in progress or a bug which should be resolved?

It is work in progress! But we need to remove inconsistencies like this anyway, I’ll follow up.
