Hi Vlad,

The working group agreed that inserting, deleting and setting the value of 
namespace nodes and root nodes is not supported and that the insert, 
delete and setvalue actions would be amended to say that requests for 
setting the value of, deleting, or using these nodes as the origin of an 
insert would all be ignored.  The XForms 1.1 specification will be amended 
accordingly and implementations can proceed with this understanding.

Thank you,

XForms 1.1 delete processing - proposed editorial clarification & proposed 
 namespace node immutability statement




Hi all, 

I noticed that in the description of the delete action processing : 
http://www.w3.org/MarkUp/Forms/specs/XForms1.1/index-all.html#action-delete 
in step 4 the deletion of the root [document] node itself is not 
explicitly 'prohibited' (or rather ignored), while the deletion of the 
'root document element' of an instance is. 
I also think, that the similar but perhaps wider clarification statement 
is required with regard to namespace nodes. The spec is explicit in 
adopting the XPath data model, as such some XPath expressions over the 
instance data can easily produce namespace nodes which do not have a full 
DOM underpinning behind them, which, in turn, makes them [arguably] 
'immutable'. 
I would like to propose to the working group (if it agrees with my point) 
to add a general statement to the spec to that effect, or at least 
explicitly mention them in delete, insert, setvalue, etc. actions as not 
fitting the bill. 

Regards, 
Vlad Trakhtenberg.
