I have been searching the archive but found very little information about
this topic (I think the information stoped with the discussion about adding
a set/get standalone method) so if I ask questions that has been asked
before, excuse me.
I would prefer that the <?xml... row in a document is treated as a
ProcessInstruction, isn't that the logical way to handle it?
Just look at the information in it the tag: version refers to the XML
version the document is created in, encoding also refers to how to handle
the characters in the document and standalone refers to if validation of the
document should be performed. So all the information is about how the
document is processed i.e. process instruction *smile*
The way to handle it would be very simular to the root element...
