radio button groups

[Pete Brunet <brunet@us.ibm.com>]

I think authors need the flexibility
to use frames an labels in the manner that best fits from the perspective
of the UI designer.  I thought of eight scenarios.  Three of
them are problematic and should be addressed as indicated below:

1) Problem:  A frame around two
radio button groups.  
Solutions:  Add labels for each
group and/or use two groups

2) Problem: A button group with no group
and no label
Solutions:  Add a label and/or
a group

3) Problem:  A label must label
controls in the same radio button group.  Although it doesn't make
sense, ODF allows this.

An example follows where the first label
is labeling controls 3 and 4 but controls 3 and 5 are in the first button
group.  This is a contrived but apparently legal example that was
submitted by Malte.

<form:form
form:name="Standard"
> 
  <form:fixed-text
form:name="LabelField1"
form:for="control3,control4"
form:id="control1"
form:label="LABEL
1" /> 
  <form:fixed-text
form:name="LabelField2"
form:for="control5,control6"
form:id="control2"
form:label="LABEL
2" /> 
  <form:radio
form:name="RadioGroup1"
form:id="control3"
form:label="Grp1-1"
> </form:radio>
  <form:radio
form:name="RadioGroup2"
form:id="control4"
form:label="Grp1-2"
> </form:radio>
  <form:radio
form:name="RadioGroup1"
form:id="control5"
form:label="Grp2-A"
> </form:radio>
  <form:radio form:name="RadioGroup2"
form:id="control6"
form:label="Grp2-B"
> </form:radio>
</form:form>


Malte, 

Are 1) and 2) detectable by the UA?
 If so our guideline can target the UA developer.  Otherwise
we need to cover this in a guideline aimed at the content author.

Can the situation in 3) be eliminated
via the schema so that it would be illegal markup?

If it's helpful here are the other five
non-problematic scenarios:

1) group with a frame
2) group with a label
3) group with a frame and label
4) two groups in one frame but each
group having a label
5) two groups with no outer frame and
each group having a label  (it's really the same as case two)
