RE: Design question

It may have been 7 mos. old, but it was helpful for me to
see the question and your answer.  I'm even more of a beginner
than you so it was a good exercise for me too.

However, a couple of things are missing from your solution...
(1) the da: namespace prefix, and
(2) capitalizing 'Positive' element name.

Below is my solution (based on yours).

However when I tried to add "da:" to the output elements,
xsl gave me an unknown namespace error unless I added
a namespace declaration to the <xsl:stylesheet> element.  Whereupon
the output da:Positive element also took on a xmlns:da="..." declaration.
I assume that's by design though I haven't thought through
why it ought to be so.

Anyway, I welcome anyone's comments on how to do this better.
