Dividing a form field into areas associated with separate entry filters

摘要

In many situations, the objective of data entry is to obtain a complex or structured value. This has traditionally been accomplished by providing a discrete entry field for each element of data entry. By extending the notion of an entry filter, and introducing the notion of a discrete editable element within an entry field, it is possible to apply a structure to that entry field. A management component enables one or more entry filters to be associated in turn with each editable element, and ensures that the entry filters are applied correctly to the appropriate elements.
