For some kinds of elements, such as <note>, you might want to vary the output format based on one or more attributes other than the outputclass attribute (see §6.3 Mapping outputclass attribute values to formats). You can specify that the values of certain attributes should modify the output format that DITA2Go uses for a block or inline element, and you can also specify a run-in heading to be included on output.
