Hi,

all my answers are based on my understanding of the new draft (21 aug. 
2002).

According to chapter 7.2, the "instance data always has a single root 
element" (unlike what the schema says), so your example is incorrect I 
think. It should be something like:
<xform:instance>
	<data>
		<project>...</project>
		<person>...</person>
	</data>
</xform:instance>

>       <label>Person name</label>

I think it should be (ref 'project' + relative ref 'name' = 
/*/project/name = /data/project/person). See chapter 7.3, point 1.

With my remarks, @ref should be /data/person/name.

Well those implementations do not follow the latest draft, nor the 
previous one.

I hope to, but I failed to see something like that in the draft.
