**Feature summary** (what you would like to be able to do and where):
A linter to generate a list of pages, where no <DT>..</DT> occurs within a <DL>..</DL> but one of more <DD>..</DD> constructions are present.
**Use case(s)** (list the steps that you performed to discover that problem, and describe the actual underlying problem which you want to solve. Do not describe only a solution):
The specific use case is identifying content Pages (ns0, nas104) , at English Wikisource, where a : construction has potentially been used to indicate an indentation, so that those uses can be replaced with an appropriate template, or poem tag usage.
**Benefits** (why should this be implemented?):
- Identify the extent of misuse of the : construction which is intended for definition lists instead of margination.
- Permit automated tools to attempt appropriate repairs based on the list generated.
