Re: Add element at the end of a variable group of ele

Hi Charles,

I'm interested to see the solutions to this problem. In particular, I'm hoping
there is a solution that can handle *no* elements before the insertion point:

<root>
 <!-- moon should go here -->
 <mars/>
</root>

as well as no elements after the insertion point:

<root>
  <foo/>
  <!-- moon should go here -->
</root>

as input. I have a similar situation where I need to insert a new element into
a schema-constrained document, and I have to consider the positions of
potentially existing (or not) elements.
