2.14. EDI to SAX Event Mapping

by an exact match on the segment code (segcode).

by a regex pattern match on the full segment, where the segcode attribute defines the regex pattern (for instance, segcode="1A\*a.*").

required: field, component and sub-component configurations support a "required" attribute, which flags that field, component or sub-component as requiring a value.

by default, values are not required (fields, components and sub-components).

truncatable: segment, field and component configurations support a "truncatable" attribute. For a segment, this means that parser errors will not be generated when that segment does not specify trailing fields that are not "required" (see "required" attribute above). Likewise for fields/components and components/sub-components.

By default, segments, fields, and components are not truncatable.

present with a value (required="true")

present without a value (required="false")

absent (required="false" and truncatable="true")
