Here is one: what's the interpretation (if any) of the unique statement
for PDUs?

Example:

list aaa {
  key "k";
  unique "b c";
  leaf k { ... }
  leaf b { ... }
  leaf c { ... }

and assume the existing configuration contains two list items:

<aaa>
  <k>k1</k> <b>b1</b> <c>c1</c>
</aaa>
<aaa>
  <k>k2</k> <b>b2</b> <c>c2</c>
</aaa>  

1. Is it possible to send the following fragment in an edit-config
(merge mode)?

<aaa>
  <k>k1</k> <b>b3</b>
<aaa>
<aaa>
  <k>k2</k> <b>b3</b>
<aaa>

That is, after merging the resulting configuration will still satisfy
the statement 'unique "b c"' (values of c are different) but the PDU
doeasn't.

2. Does "unique" and also "key" statements assume any space
normalisation? For example, are the following keys different?

<k>k1</k>

<k>
  k1
</k>
