Properties in documents can be referenced. In a select clause specifying "Name, Short Description" selects the Name and Short Description property. If a property value is a link, a special syntax allows to fetch a property from the referenced document. The syntax for a deep link is '->'.

Person->Address->Phone

Deep links may also be specified in templates (for instance using the Display Document Properties Macro) and in where clauses (for instance using the Display Table Macro).
