[jdom-interest] Convoluted Document Construction on b10

[Stefano Santoro]

Jason,

thank you for explaining it. We are now shipping an MMS Storage
solution to cell providers like Cingular that is heavily based
on XML technologies (Oracle XML/DB, Style Sheets) JDOM plays
a central role in this solution for being one of the quickest ways
to build documents. Which JVM we ship this product on?

   Sun JDK 1.3.1_08
  
We may consider going to the 1.4+ series for the next major 
release.

So you can understand that when you say that you are preparing for 1.5
covariant return type feature, it means for us that jdom at b10+ will
be unusable for at least another three years.

May I suggest that you extend the Parent interface with the
following method?

Content asContent()

Ciao
Stefano
