Re: Added context everywhere (by adding it to the binding attributes)

Leigh,

I've updated the relax-ng and xml schema. But if you'd like to review the changes that would be nice. This https://dvcs.w3.org/hg/xformsusers/rev/153bae3cf078 is the relevant change set.

If you have time, it would be great if you could review my other changes to the the schemes https://dvcs.w3.org/hg/xformsusers

Kind regards,

Ah, thanks, I doubt it.
Nick mentioned the XML schema at one point, but it might have been for context and not model...

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
