	* XmlSchemaDataImporter.cs :
	  SimpleContent column support.
	  Annotated relation support.
	  Top-level element is counted only when its type is complex.
	  xs:anyType is no longer treated as complex type.
	  dataset existence is mandatory now.
	  Improved DataType and DefaultValue support.
	  Attribute namespace is properly handled now.
	  Prohibited attribute is now treated as hidden column.
	  Reject list or union simple type.

	  Still incomplete 1) to read relationship in some cases, 2) to
	  determine whether an element is dataset or table, 3) thus to
	  exclude extraneous column, 4) to remove extraneous *_Id column.
