Second Draft progress: https://github.com/w3c/matf/issues?q=is%3Aissue%20state%3Aopen%20milestone%3A%22Second%20Draft%22

Changes between First draft and Second draft: https://services.w3.org/htmldiff?doc1=https%3A%2F%2Fwww.w3.org%2FTR%2F2025%2FDNOTE-wcag2mobile-22-20250506%2F&doc2=https%3A%2F%2Fw3c.github.io%2Fmatf%2F

Definitions drafts - Diagram

https://deploy-preview-293--wcag2mobile.netlify.app/#figure1

Part of this Pull Request: w3c/matf#293

Old version: https://github.com/w3c/matf/blob/3030d32a7ce5660e43cf9e1b6915ace89589cd0e/layers.svg

New diagram: https://github.com/w3c/matf/blob/a48d07d819bc7dd17554cef1748bc3731b0c08fd/assets/layers.svg

Software or User Agent: renamed to Software

"underlaying layer" renamed to Hardware

Native program / Cross-platform program renamed "program" to "app"

Title updated to reflect content, it's now "Layers and responsibilities in mobile applications"

Prefixed the layers with numbers, e.g. "1. User" instead of "User"

Added dotted square around native app / cross-platform app, together named "Application Software"

<Joe_Humbert> Looks good to me

Diagram label section, could be made bigger by moving them to the left edge - gives extra space on the right

In the detailed description, use uppercase for each word

Definitions drafts - Application software

https://deploy-preview-293--wcag2mobile.netlify.app/#application-software

Now contains a table

Application software - do we need to define what platform widgets mean

React Native can render native platform widgets; but what about custom components (or native apps with custom components)

Potentially second column can be removed to just provide examples of the types of apps and the frameworks that correspond

Semantics tree might also need definition

First sentence is OK

Second sentence: introduce the different ways that application software is built, point to table 1 with examples

Success Criterion 2.5.7 Dragging Movements

github.com/w3c/matf/pull/295

The concerns about "underlying layer terminology" should now be resolved because the diagram no longer uses it, so underlaying now refers to one layer below and not some other definition

Success Criterion 2.5.8 Target Size (Minimum)

https://github.com/w3c/matf/pull/291#discussion_r3683331365

We need to decide which language to use in the note that links to the research, plus how to introduce our suggested target sizing

^ relates to note 3
