I meant I will try to get to the RNC schema updates to align with the
spec, unless someone else hasdone it.

Hi Leigh, 

Do you mean just that you will try to get to reading the changes? 
We did already change the spec to reflect these.  I'm just letting you
know that we did some good fixes as a result of your feedback.  So you
don't have to do anything more... unless you see a place where we need
to make any further fixes. 

Thanks again,

Hi Leigh, 

Further response to this line of inquiry: 
- Yes context goes everywhere, so we moved it to the Common group 
- As a result, the model attribute had to be moved to the Common group,
which applied model in places not previously applied 
- The bind element is explicitly restricted to binding to the current
model, if the model is expressed, to avoid cross-model computation
dependencies. 
- The header and var elements are not restricted in terms of the model
to which they can bind as they are like actions, which are not
restricted from referring to another model. 
- As Nick previously responded, model and context apply to any kind of
binding. 
- Actions such as rebuild, recalculate, revalidate, refresh and reset
were amended to remove model as a special attribute, since it is in
Common. The text was changed to use the model of the inscope evaluation
context instead, along with a Note indicating that the model attribute
could be used to change the context. 
- Actions and their children/descendants, such as dispatch and its
children, get context and model.  For example, it is at least feasible
(if not terribly useful) to get the dispatch name from the data of one
model and the dispatch targetid from the data of another model.

There is still a distinction between 
single-node binding: @model, @ref, @bind 
and 
sequence-binding (formerly nodeset) binding @model, @ref, @nodeset,
@bind 
In that single-node-binding is used on 
label, hjelp, hint, alert, message, item/value, item/copy,
upload/filename, upload, output, output/mediatype, input, textarea,
secret, select,select1, range, trigger, submit, load, setvalue, group,
switch, 
and sequence-binding is used on 
itemset, insert, delete, repeat. 

Q: Does @context go on both single-node-binding and sequence-binding?

Q: Also, does @context go in any of the following places, which
currently have @nodeset, @ref, or @model: 
header, bind
other actions (rebuild, dispatch, send, setfocus, etc)
var
