MySQL
当从MySQL数据库（DB）生成XML Schema时，MySQL DB数据类型会被转换为下表中列出的XML Schema数据类型。
XML Schema数据类型 | MySQL数据类型 |
xs:ID | varchar(255) |
xs:string | If no facets then varchar (255) |
| else if facet length is set and <= 255 |
| else if facet maxLength set and <= 255 |
| else if maxLength is set and <= 65545 then text |
| else if maxlength is set and <= 16777215 |
| else if maxlength is set and <= 429496295 |
