Confluence allows to organize pages in a page hierarchy. Each page has a parent page, a parent page may have zero or more children. With the PDAC1 a page becomes a projectdoc document. A projectdoc document is a Confluence page with properties and sections. There are a couple of properties commonly used by all projectdoc document types. 'Commonly' indicates that there are no hard rules that a document type is required to define those properties, but the document types we define use these properties by convention.

One such property is the Parent Property. While the parent Confluence page relationship is defined by the location of two pages (one page is the child of another and this defines a hierarchy made obvious by the breadcrumbs), the parent projectdoc document relationship is a virtual one.

What does this mean and is this useful for anything?
