I've uploaded the first cut the selection API specification unofficial draft at https://github.com/rniwa/selection-api

I've modernized and rephrased the text; e.g. the spec refers to browsing context instead of defaultView, and defines selection's range being null as being "empty".

Finally, I've turned all Aryeh's comments and notes into notes that are visible.  We can remove those comments as we solidify the spec. and get implementation reports.


As mentioned in the spec (thanks to Aryeh), there are 11 serious open issues in the current draft.  The most serious one is that stringification of selection is completely undefined due to its dependency on innerText, which in turn is also undefined.

Given defining innerText is completely outside the scope of the selection API specification, we might need to defer this part to a level 2 specification since the only alternative is to wait for someone to write a innerText spec.


While I completely forgot to mention at F2F today, I'm looking for a test facilitator.  Aryeh has already written some tests in https://dvcs.w3.org/hg/editing/raw-file/tip/selecttest/ so he/she just needs to import those into web-platfrom-tests repository on github, and modernize them as needed.

As a result, the specification hasn't made much progress towards reaching Last Call or CR.
