MySQL
Wenn anhand einer MySQL-Datenbank (DB) ein XML-Schema generiert wird, werden die MySQL-DB-Datentypen, wie in der Tabelle unten aufgelistet, in XML-Schema-Datentypen konvertiert.
| XML-Schema-Datentyp | MySQL-Datentyp | 
| 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 |
