33 /**
34  * The style-mapper holds all information about the OpenOffice style mapping
35  * mechanism. OpenOffice references styles by their name and context, a style
36  * has a style-family assigned. The style family is determined by the element
37  * referencing the style, and there is no easily accessible information
38  * available on that.
39  * <p/>
40  * Therefore this mapper acts as gatekeeper for this information. The style
41  * mapping information is read from an external definition file and can be
42  * maintained externally.
