Id like to stop working on the current HTML to Platform A11y APIs document and create and start working on the new HTML5.1 user agent implementation guide following the proposed outline. 

Should a new repo be created in Github, or is there a better place for it under one of the existing repos?  I note that a blank SVG implementation guide has been created under the ARIA repo at https://github.com/w3c/aria. If we are going to use the ARIA repo for all these implementation guides, I suggest they all go in the implementation folder in the ARIA repo at https://github.com/w3c/aria/tree/master/implementation. That way they can at least share style and script resources, which might be handy.

But perhaps there is a better way. Open to suggestions.

For those new to this these are the accessibility API mapping guides that browsers must follow in order to support a host language or cross-cutting markup like WAI-ARIA. The ARIA 1.0 User Agent Implementation Guide, now a W3C Recommendation (http://www.w3.org/TR/wai-aria-implementation/), is the first industry document to achieve do this.

Shane McCarron is converting the existing documents to be based on Respec and the editors are reading up Respec. and Github. The ARIA 1.1 specification will also be based on Respec. and will go to Github versioning.
