This property allows template authors to control the title of a document dependent on the expected parent's doctype defined by the Parent Document Property.

Per default the title of a new document will only be adjusted by the parent document's title if the parent page is a semantic parent document. The parent page is a parent document if the Parent Document Property is not empty. This property allows to override this and accept any document to be the semantic parent. This is espcially especially useful for document types that are not closely related to a specific the parent document type, such as Section or Step.
