There's been some movement on the caret tracking proposal:
http://www.w3.org/Bugs/Public/show_bug.cgi?id=11239

There still seems to be some confusion over the TextMetrics.baseline attribute,
which will apparently need to be "rectified by a future,
separately raised proposal that provides sufficient detail".

If there are any of you on the list that are up for reviewing the prior
proposal, and providing feedback, I'd appreciate it. I posted clarification
of the section on the bug report.

metrics . baseline
"Returns the vertical offset of the anchor point for the text that was passed to the measureText() method"
http://lists.w3.org/Archives/Public/public-html-a11y/2011Feb/att-0162/HTML_Canvas_2DContext20110217.html


The term -anchor point- is defined in the preceding section on textBaseline keywords.
"The textBaseline attribute's allowed keywords correspond to alignment points in the font...
Let the anchor point be a point on the inline box, determined by the textAlign and textBaseline values"


Here's the link to the working group decision on caret tracking, including TextMetrics:
