Making a plea for feedback, the World Wide Web Consortium (W3C) is calling for a broad review of HTML5 and five related specifications that constitute the W3C Open Web Platform.

HTML5 upgrades HTML to accommodate modern web applications, covering multimedia capabilities. W3C said it is actively seeking feedback at this stage of the standards process. The W3C HTML Working Group is inviting broad review through August 3.

"We now invite new voices to let us know whether these specifications address a broad set of needs," said Tim Berners-Lee, W3C Director, in a statement released by W3C. The working group also invites contributions to the HTML test suite, which is important for interoperability.

"We're seeing interest in HTML5 everywhere, and I am very excited that HTML5 has reached Last Call," said Philippe Le Hégaret, the W3C manager responsible for HTML5, CSS (Cascading Style Sheets), SVG (Scalable Vector Graphics, WOFF (Web Open Font Format) and other user interaction technologies. "The HTML Working Group is W3C's largest group with over 50 W3C Members and more than 200 invited experts. Reaching agreements in this large a community is a tremendous achievement."

Feedback on the specifications, listed below, can be entered by following instructions on the accompanying links:
