<?xml version="1.0" parser="yes"?> utilizes a real XML parser
<?xml version="1.0" parser="no""?> server MUST send simple XML as defined by the draft
<?xml version="1.0" empty-tags="long"?> needs <empty></empty>
<?xml version="1.0" accept-charset="ISO-8859-1"?> (I don't think introducing <?rpc ... ?> was a good idea, even if 3470 has a similar example. ;)
But as these xml processing instructions then didn't actually apply to the document they were in, but instead control how the server reply should be constructed - wasn't this then abuse of this tag form?
