List items are fragile in wikitext and there are many things (e.g. tables and images) that cannot be effectively embedded in lists. The Editing Team and Parsing Team are seeking your input on a proposal to introduce new wikitext syntax that will eliminate the aforementioned constraint and unlock new possibilities for people using wikitext talk pages.

You can find information about what is being proposed and how you can help shape it below.

Participate
The teams need to know what you think about this proposal. Specifically, the team is curious to know how you will answer the following questions:
 * 1) Of the proposals listed below, which do you think would best satisfy the requirements?
 * 2) What alternative approaches do you think should be considered?
 * 3) For each of the proposals listed below, what other advantages, disadvantages and/or unknowns do you think should be considered?

In addition to the above, the teams would also value hearing what other questions and ideas the proposals lead you to think about.

Motivation
This section contains information about why this particular change is necessary and why making this change now is a priority.

Existing problems

The lack of explicit syntax for multi-line comments limits the thoughts people can represent in the conversations that happen on wikitext talk pages. Specifically, this means:


 * Contributors are limited in the types of things (e.g. tables and images) they are able to embed in lists (read: indented talk page comments). This inhibits them from being able to communicate about and collaborate on components like navboxes, series templates, and infoboxes within indented comments on talk pages. When contributors really need to use such features, they'll sometimes break out of the indentation structure, making it harder for readers and algorithms to understand the structure of a conversation.
 * Contributors are not able to create visual line breaks within talk page comments without using HTML code or local templates.
 * Contributors face a higher risk of markup errors contained with talk page comments posted using DiscussionTools "leaking out" and corrupting content elsewhere on the talk page.
 * Contributors who use screen readers have a more difficult time understanding conversations, and subsequently participating in them, because the tools they use are not able to properly narrate/speak/announce the comments in a talk page conversation. Source
 * People using features like the new Reply Tool are not able to use templates, tables and extensions in the tool's  mode.

New opportunities

In addition to the resolving the issues listed above, introducing syntax for multi-line comments would enable people to:


 * Edit specific comments on talk pages. This is functionality that had been planned, but became blocked because of this lack of syntax. For more information, see: T242562#5897905.
 * Build new gadgets that extend talk page functionality because comment parsing would become more reliable.

Requirements
This section contains the requirements any proposal must need for it to be adopted.


 * The new new syntax must enable people to include components[i] that span multiple lines within an indented list item.
 * The new syntax must not break existing content on talk pages
 * People need to be able to recognize the new syntax as being wikitext[ii]
 * People should be able to easily understand the meaning/function of the syntax by reading it context
 * The mew syntax needs to be interoperable with existing-and-future list-item talk page markup
 * The new syntax must work across all languages and be reasonably convenient to input using different text input methods.
 * The new syntax must be compatible with the core parser.
