The ApplicationRef element is meant to relate the parent element (Product, Representation, etc.) back to the owning entity in the sending application. ApplicationRef has the following attributes:
| Attribute | Namespace | Type | Use | Default | Fixed | Description |
|---|---|---|---|---|---|---|
| externalRef | ocx | xs:string | req. | URI specifying the file location of the referenced entity. | ||
| name | ocx | xs:attribute | req. | Custom property name | ||
| localRef | ocx | xs:IDREF | opt. | A reference to a unique ID within the scope of this XML file. Either a localRef or a GUIDRef shall be provided, or both. The schema will check this by the assertion: test=“(@localRef and not(@ocx:GUIDRef)) or (not(@localRef) and @ocx:GUIDRef) or (@localRef and @ocx:GUIDRef)”. | ||
| GUIDRef | ocx | ocx:guid | opt. | A globally unique ID referring to an entity in the authoring application. The sending application creates and holds the GUID. Used to establish a unique reference to an entity persistent between applications. |
