All of the Skotos games use XML for exchange, i.e. internally objects
are stored as DGD persistent objects, but all can be exported and
imported as XML. We make no attempt to try to be totally faithful to the
various XML issues like DTD vs. Schemes, etc. We also have some XML
'shortcuts', dynamic object handles, and an XML control language called
SAM, that allow us to do interesting things with dynamic content that
might break a purist XML parser.

However, that we do as much as we do with XML and have multiple games
proves at least it can be done.

Enclosed is a simple example rose in our example directory, that shows
our XML for a simple object.
