"""
PropertySets group common attributes together, each property set is used to control a specific part of the rendering.
PropertySets can be used in different elements of the document.
For example the FramePropertySet is used in paragraphs, tables, cells, etc.
The TextPropertySet can be used for text or in a Paragraph Style.
