Bug 120036 Preview of XML attributes is not working
The XML attribute values are not working in the current BIRT XML ODA driver. Only 'text'-type XML elements' values are displayable in Preview. ColumnMapping XPath expressions like "@attributeName" are broken in Preview. I'll attach document showing the problem and sample XML/XSD data

		return ( (ColumnInfo) this.columnInfos.get( columnName ) ).getColumnType( );
	}
