RE: Definition of baseline

We had written an introduction to baseline document and it was posted at

This was linked from within the introduction section of the WCAG 2.0 Jan 17
However this appears to be a dead link now. Does anyone know where it went?

What are we thinking a baseline will actually look like in written

We have a doc on it somewhere.  Have to look for it.

It was discussed in the 17 November telecon:

I imagine that some people would be interested in a machine-readable 
baseline definition, for example in RDF.

I also wonder if just listing technologies is a bit too simplistic: it 
assumes that all features of a technology are supported, including, for 
example, in the case of HTML 4.01, the object element, the optgroup 
element, the link element for navigation, and the longdesc attribute. 
(Since support has been getting better these are not the best examples, but 
SVG support has similar issues.) What if authors use embed instead of 
object? This can happen when the customer sets the baseline (see note 4 in 
Gregg's proposed definition) and wants embed instead of object.
If someone (customer and/or developer) decides that certain a repair 
technique will be used because the preferred markup feature (that would 
fulfill the same purpose) is not sufficiently supported, should it be 
possible to exlude that markup feature from the baseline? If yes, that 
would provide a mechanism to explain the presence of the repair technique.
