+<p>These are java archives of an XML file containing alignments, trees and Jalview
+ display information. A data exchange standard is currently being developed,

+<p>For those who want to know...<br>
+ Jalview uses java classes automatically created using <a href="http://www.castor.org">Castor</a>.
+ Jalview 2.08 uses descriptor classes which significantly increase the speed
+ of marshalling / unmarshalling java objects into XML. Files created prior to
+ Jalview 2.08 can still be read in, but they will be saved in the new format.
