Summary: Xml document which begin with an empty line

Initial Comment:
In a xml document which begins with an empty line, for
example:
"""Start here"""

<?xml version="1.0" ?>
<bugged></bugged>
"""End here"""

Expat give this parse error: 
XML Parsing Error: xml processing instruction not at
start of external entity.
I discoverd this bug when I tried to pass an xhtml
document to firefox via ASP.NET with the
"application/xhtml+xml" content-type.

>From the XML spec:
[1]    document    ::=    prolog element Misc*
[22]    prolog    ::=    XMLDecl? Misc* (doctypedecl Misc*)? 
[23]    XMLDecl    ::=    '<?xml' VersionInfo EncodingDecl? 
SDDecl? S? '?>' 

Which means that it is an error if an XML document starts
with an empty line. So Expat is OK. However, Expat's error
message could be improved to say: "XML/Text declaration
not at start of external entity".

So maybe we should change the message.
