I'm sharing with you and the others on this list the
internal working group's "laundry list of open questions",
what constitutes the details of each level. Below are
the questions, the working group is currently working on
the answers. Until now, we are discussing the Basic and
Full level. The XForms Core level is new (came out of this
discussion based on Joern's feedback) and the working group
still has to discuss and agree on it before we can consider
it.
But any proposals from you or the others for answering those
questions might help the working group to find the right
decision on these very sensitive, critical issues.

The following sections don't clearly identify whether they are part of
XForms Basic or Full:
Chapter 2 "Concepts"
- Overall. Are the examples here Basic or Full?
Chapter 5 "The XForms Model"
- For each model item property: Full or basic?
(type, readOnly, required, relevant, calculate, isValid, minOccurs,
maxOccurs)
- For each binding constraint need to state Basic or full
- Allowed inline Schema for Basic vs. Full
Chapter 6 "XPath Expressions in XForms"
- All methods defined here need to state ...
Chapter 7 "Form Controls"
- All form controls need to state ...
- All common markup needs to state ...
Chapter 8 "XForms Actions"
- All XForms Actions need to state ...
Chapter 9 "XForms User Interface"
- All aggregate form controls (group, repeat, switch, component) need
to
state ...
Chapter 11 "Processing Model and Conformance"
- Serialization methods ("xml", "urlencoded", "form-data") need to
state
...
