Not only is maintaining the order a good idea, its
required for properly handling documents that will be
validated against an XML Schema. XML Schemas are
allowed to specify the order that elements appear in.
If JDOM did not maintain this order, then reading a
document into JDOM and outputting it back to an XML
string could take a valid document and make it
I don't think it is an accident that the current JDOM
preserves the order of elements, and hopefully this
thread will be a reminder to any potential
contributers that order can matter in an XML document,
and so should be preserved by JDOM.
