Provides a list of properties and their values for each library content. There will be one row in this table for each property value on a piece of content. A library content tagged with 2 single value properties and 1 multi-value property with 3 values would produce 2 + 3 = 5 rows in this table. A library content with no property values assigned will not be present in this table. Each row represents a single value of a single property on a library content.
