All XML elements are case sensitive. For each element, follow the capitalization that is defined in the schema.

Elements must appear in the control file in the order in which they are defined in the schema. Your XML editor should indicate the allowable elements at each point in the control file.

Observe the properties that are defined for each element in the schema file. For each element, the schema file might define the following properties, depending on the data type:

Name
Cardinality, that is, the minimum and maximum number of occurrences
Type
Valid values
Minimum and maximum length
