1. Could you please give an example or a link to the
XML-specification to point out why a newline after
XML-declation or at the end of the file should make the 
XML illegal. I am NOT talking about your problems
to implement this properly, but why
<?xml ....?>^n
<root>...</root>^n
should be illegal!?!?

2. Having a newline after XML-declaration as well
as at the end of the file is a common need that
JAXP users have. I can NOT accept your point
saying that this is generally NOT supported because
it could cause some trouble you may have implementing this.
This has a large impact after everybody has to eat this
when just using a plain JDK. It is a lot worse if people
start adding newlines manually to OutputStream,
because this will cause real trouble with encodings, especially
if the encoding is NOT 8-bit-wise (e.g. UTF-16) and a newlines
get broken because hackers of such workaround do NOT think
of such problems.

Please provide a solution here.

Thanks
  Jörg
