SharePoint field definition field element name Attribute Value List in XML file

The field element child level of the fieldtype element will be configured in the fldtypes *. xml file in % ProgramFiles % \ common files \ microsoft shared \ Web Server Extensions \ 14 \ template \ XML.

Each fieldtype element has several required and optional field elements, which are distinguished by the name attribute. The following table describes these elements. In the object model, the field type is represented by the spfieldtypedefinition class. This class has the read-only attribute corresponding to all rows except the two rows in the table. (The rows with the two exceptions are internaltype and sqltype .) Unless otherwise specified, the property name matches the value of the corresponding name attribute.
