Since then\, that question has turned into a real problem o n live sites. Several browser agents now tell web developers to add `aria- label` and `aria-description` attributes to buttons\, links\, and inputs s o agents can tell what a page does. Because ARIA overrides visible text an d feeds straight into screen readers\, stuffing prompts and agent instruct ions into accessibility attributes breaks the experience for screen reader users.\n\nAt the same time\, browser engines and web developers are debat ing how much of the agentic web should rely on existing HTML "as it is spo ken" versus new declarative markup or imperative tool APIs like [WebMCP](h ttps://github.com/webmachinelearning/webmcp). Many web interactions are si mple\, stateless actions where writing a JavaScript tool handler is overki ll\, but standard HTML and existing structured data don't always make it o bvious what a control does or whether an agent is safe to trigger it.\n\nA longside related sessions on [AI-friendly webpages](https://github.com/w3c /tpac2026-breakouts/issues/23)\, [declarative and imperative solutions](ht tps://github.com/w3c/tpac2026-breakouts/issues/24)\, and [extending WebMCP ](https://github.com/w3c/tpac2026-breakouts/issues/36)\, this session gets the accessibility\, HTML\, structured data\, and WebML communities in the same room to talk through concrete markup trade-offs:\n\n- **Keeping ARIA for accessibility:** Why are agent builders telling developers to overloa d `aria-label` when semantic HTML elements and forms already exist? Can be tter browser heuristics on standard HTML solve this\, or do developers nee d a simple way to describe controls for agents without breaking screen rea ders?\n- **Standard HTML and Schema.org vs. new attributes vs. imperative tools:** For everyday page actions like search\, filtering\, and cart upda tes\, how far can standard HTML forms\, Schema.org Microdata\, and JSON-LD get us? Where is the clean handoff between declarative markup in the DOM and registering JavaScript tools via `navigator.modelContext.registerTool` ?\n- **Safety hints and human-only controls:** Should HTML have a declarat ive way to mark the risk of an action\, like separating read-only navigati on from actions that change state\, spend money\, or always require a huma n click? And since careless or malicious sites can mislabel controls\, how should browsers and agents treat safety hints from a site?\n- **Working w ith existing browser signals:** How should agent semantics fit with featur es browsers already have\, like form autofill\, password managers\, and lo gin status APIs\, so developers don't have to describe the same flow three times?\n\n**Goal(s):**\nWork out how far standard HTML and existing struc tured data can go for everyday agent actions\, how to keep agent instructi ons out of ARIA\, and where declarative HTML hands off to imperative APIs like WebMCP.\n\nAgenda\n\n- **First 10 minutes:** Quick recap of what we'v e seen since TPAC 2025\, including how agent docs are telling developers t o misuse ARIA and where standard HTML forms hit their limits.\n- **Next 15 minutes:** Keeping ARIA for accessibility\, and comparing standard HTML\, Schema.org\, new HTML attributes\, and imperative WebMCP tools.\n- **Next 20 minutes:** Marking safety boundaries in HTML\, from read-only actions to state changes and controls that always need a person\, and how browsers should handle untrusted hints from sites.\n- **Final 15 minutes:** Where browser engines\, accessibility leads\, and agent builders agree or disagr ee\, and where this work should live next.\n\n**Materials:**\n- [Session p roposal on GitHub](https://github.com/w3c/tpac2026-breakouts/issues/69) STATUS:CONFIRMED CREATED:20261013T144652Z LAST-MODIFIED:20261027T172855Z SEQUENCE:3 ORGANIZER;CN=W3C Calendar;PARTSTAT=ACCEPTED;ROLE=NON-PARTICIPANT:mailto:nor eply@w3.org LOCATION:Ground Floor - Lansdowne Room CATEGORIES:TPAC 2026,Breakout Sessions END:VEVENT BEGIN:VEVENT UID:64686588-939d-4d6d-8781-30a69c264be2 DTSTAMP:20261027T172729Z SUMMARY:Bringing Private Access Control Tokens to the Web DTSTART;TZID=Europe/Dublin:20261026T170000 DTEND;TZID=Europe/Dublin:20261026T180000 DESCRIPTION:https://www.w3.org/events/meetings/64686588-939d-4d6d-8781-30a6 9c264be2/\n\n[PACT](https://hacks.mozilla.org/2026/06/pact-anonymous-crede ntials-for-the-web/) is a [shared effort](https://www.cloudflare.com/en-gb /press/press-releases/2026/cloudflare-collaborates-with-leading-browsers-t o-develop-a-privacy-first-protocol-for-the-global-internet/) to develop a privacy preserving protocol which can enable user-agents to bypass CAPTCHA s and block pages\, without compromising either user privacy or the effect iveness of sites' anti-abuse tooling. \n\nIn this session we'll talk thro ugh the problem PACT is trying to solve\, the proposed solution\, and seek feedback on the approach from the community.\n\n**Goal(s):**\nShare persp ectives and concerns about PACT\n\nAgenda\n\n**Materials:**\n- [Session pr oposal on GitHub](https://github.com/w3c/tpac2026-breakouts/issues/29) STATUS:CONFIRMED CREATED:20261013T144450Z LAST-MODIFIED:20261027T172729Z SEQUENCE:3 ORGANIZER;CN=W3C Calendar;PARTSTAT=ACCEPTED;ROLE=NON-PARTICIPANT:mailto:nor eply@w3.org LOCATION:Second Floor - Room 09 CATEGORIES:TPAC 2026,Breakout Sessions END:VEVENT BEGIN:VEVENT UID:c4735ea4-45e6-4b31-9689-d1072871f5d5 DTSTAMP:20261027T172727Z SUMMARY:Cybernetic Avatar CG Discussion DTSTART;TZID=Europe/Dublin:20261026T170000 DTEND;TZID=Europe/Dublin:20261026T180000 DESCRIPTION:https://www.w3.org/events/meetings/c4735ea4-45e6-4b31-9689-d107 2871f5d5/\n\nCybernetic Avatars (CAs) are technologies that extend human c apabilities through remote\, robotic\, and digital embodiments\, enabling people to interact with other people and environments beyond physical cons traints.\n\nFollowing the introductory discussion from our previous TPAC b reakout session\, this session will provide a brief recap of the Cyberneti c Avatar concept and share updates on our recent activities\, use cases\, and validation efforts.\n\nIn particular\, we would like to explore the po ssibilities for implementing and supporting Cybernetic Avatar interactions through Web technologies and browser-based environments.

Uncovering the Main Topics of Interest in the W3C](https://doi.org/10 .1145/3774905.3795481)". The paper investigates the main areas of interest of organizations participating in W3C by applying topic modeling to publi cly available data on member organizations' participation in W3C groups\, using the number of representatives assigned to each group as a proxy for organizational priorities.\n\nThe analysis identifies five major areas of focus: Browser\, Ads & Privacy\; High Performance\; Credentials & Web of T hings\; Accessibility\; and Payments. It also shows that large enterprises \, particularly those based in the United States\, dominate participation in browser development and advertising-related work\, while Japanese organ izations are more strongly represented in Web of Things activities.\n\nThe session will begin with a presentation by the paper's lead author\, follo wed by an open discussion with the audience.
