That XML declaration matter is technically no prolem - even if
you are using "new XmlTextReader (Stream, XmlNodeType, 
XmlParserContext)", you don't have to worry that the input might not
be parsed with the declared encoding. A wrapper stream is there that
detects encoding declaration from the stream.

Am also wondering if there should be both "MS compatibility mode" and
"Mono improved mode" respectively, by the importance of the bugs.

For binary compatibility, it would be provided by configuration
settings (that would be nasty code since inside System.Xml we cannot
use ConfigurationSettings class in terms of the build order).
