RE: Minimal content model for xf:group and text

Even if we have already decided this in the past for group, repeat, and case and it is just test suite issue, we still have a problem with label, which doesn't allow text in the XSD schema.

Hi Leigh, 

We have already fixed a number of other tests in which the test author forgot to put a surrounding label on the text, and 4.6.3.a should be similarly fixed (The test as currently written would need such a feature, but the test does not require mixed content for what it is testing.) 

It is better to leave the presentation of text as part of the overall enhancement to container control content models that may optionally be performed by host languages.  For example, we would like to see ODF improved in the future to include XForms form controls, not just the XForms model, but in ODF the text and form controls are at different layers, so there would be an indirection involved in connecting them.

Owen Newnan reports that test 4.6.3.a uses text as direct child of xf:group, yet the minimal content model of xf:group does not allow text. 
  
The XForms 1.1 XSD schema comments that the host language should add to the content model of group, case, and repeat, but doesn't include text per se. 
The test case 4.6.3.a though clearly requires it. 
  
The RNC schema allows UI Inline content under group, repeat, and case, but I can't find a justification for that in the XForms 1.1 Recommendation. 
  
Here's what I did find in the recommendation: 
- Element xf:label is described as having "inline text" and it's in the XSD and RNC schemas a UI Inline, but there's no explicit mention of "UI Inline" in the prose. 
- Non-toplevel elements generally don't have a table specifying Minimal Content Model, so that may be why the prose for xf:label has some statements about text. 
- Element xf:message does have a Minimal Content Model and does allow text: PCDATA|UI Inline. 
  
We might want to consider adding to the errata list that the minimal content model for group, repeat, and the prose for case to include PCDATA|UI Inline. 
  
Or do we consider presentation of text (other than label and message) to be wholly a host language issue? 
  
Leigh.

Subject: whether text content should be allowed in controls

Leigh, 

As regards message 
Chapt04/4.6/4.6.3/4.6.3.a.xhtml:49:24: cvc-complex-type.2.3: Element 'xforms:group' cannot have character [children], because the type's content type is element-only. 

with content 
<xforms:group>
When a value is selected you must see the output "xforms-select". The value in
parentheses
indicates which form control the event came from,the select or select1 control.
The output may be followed by the output for the Value Change sequence ("xforms-recalculate",
"xforms-revalidate", "xforms-refresh", and "xforms-value-changed").
</xforms:group> 

Looking over the spec it's not obvious wto me hether text content should be allowed in controls (it obviously is in instances). Please advise.
