The type, location and error attributes are used to control the method for generating formatting characteristics for an element and are set during the generation of layout markup. These attributes should not be modified.
The attributes attr1 through attr9 are generic attributes that can be used by the application writer to customize page layout applications. By convention, attr1 is used to display automatically generated text, such as line numbers.
