ISSUE-205: caret-location-API - Chairs Solicit Alternate Proposals or Counter-Proposals

'Define what author guidance and/or methods should be provided to those 
that wish to create accessible text editors using canvas as a rendering 
surface'

The current status for this issue:

http://www.w3.org/html/wg/tracker/issues/205
http://dev.w3.org/html5/status/issue-status.html#ISSUE-205

So far, we have two Change Proposals submitted for ISSUE-205:
http://www.w3.org/html/wg/wiki/ChangeProposals/CaretSelectionRevised
http://www.w3.org/wiki/No_edit_change_proposal_for_canvas_text_editing

At this time the Chairs would also like to solicit additional Change 
Proposals, in case anyone would like to advocate the status quo or a 
different change than the specific ones in the existing Change Proposal.

If no counter-proposals or alternate proposals are received by March 
14th, 2012, we will proceed to evaluate the change proposals that we 
have received to date.

Note: this issue was split off ISSUE-131.
