	* DataSet.cs :
	  - In MS output, XML declaration looks to have standalone decl (yes).
	  - ReadXml(reader) just calls to ReadXml(reader, XmlReadMode.Auto)
	  - ReadXml(reader, mode)
	    1) return originally specified mode, instead of (always) Auto.
	    2) Check empty reader.
	    3) Check diffgram schema and content separately.
	    4) When diffgram exists, remaining (the same-level) contents
	       won't be consumed.
	    5) Similar fact should be applied, but somewhat different.
	       InferSchema and IgnoreSchema just skips, Fragment reads both
	       schema and content, others just reads schema.
	  - Removed unused code.
	* XmlDataLoader.cs :
	  - Read() should skip in some ReadMode.
	  - Don't compare schema element name as case-insensitive (well,
	    should schemas be checked here?)
	  - Avoided BuildDocument() not to create confusing DataSet
	    document element.
	  - Don't add any tables when reader has single element.
	* XmlDiffLoader.cs :
	  When target table was not found, MS.NET doesn't raise an error.
	* XmlSchemaMapper.cs :
	  When XmlSchema.Read() left xml reader at </xs:schema>, read once.
