The Paragraph Style attribute can store as many <attribute: style> pairs as you want.
The value of the Paragraph Style attribute is object specific, but it can contain style information for more than one attribute. You could, for example, specify one style for the Object Heading attribute, and a different style for the Object Text attribute. If you then exported the object, Word would apply different styles to the data in each attribute.
The tool can manipulate the styles either for the current object or for every object in the current view.
You can specify a default style which applies to every attribute that is not listed in the Paragraph Style attribute.
You can specify styles for data that is not an attribute value, such as layout DXL and object identifiers.
