To be fair, Ian created the split as a response to the bug I filed (as requested by Sam) requesting this change. This was based on all the previous discussions on this topic. Eliot has been continuing to edit the document that Doug started and put a fair amount of effort into this. The content of the spec has been in some limbo waiting for the split from the main HTML5 spec to happen. As I proposed previously, I think Eliot's version should be modified to delete section 2 and only define the 2D context API. I believe this is compatible with the change Ian has made.

The HTML working group already made a formal decision that canvas was in scope.

This was the basis for my proposing the separate canvas spec.

We've been trying to follow the process. I filed a bug. Ian dealt with and resolved the bug. If Ian had disagreed then I would have written a change proposal. With the change incorporated into the spec, we now need to address the issue of where the canvas API is defined. Eliot is now intending to update his draft to be compatible with the split that Ian has made. Ian also has an API draft.  With the work that Eliot has put into editing the version he took on from Doug, we'd like to continue to edit that document. The document isn't ready for FPWD yet but we'd like to move in that direction. Alternatively, Ian's document might be the definitive 2D API and that move to FPWD. The working group should come to agreement about which outcome is desirable.

Regards,

Adrian.
