Transclusion and Inherited Suffixes?

Hi,

the DocBook Transclusion draft[1] defines three attributes:
trans:suffix, trans:linkscope, and trans:idfixup.

According to the spec, trans:suffix is definied as:

  suffix

    * Defines a value to be appended to all ID values on the element
      (elements and attributes whose values should be treated as IDs
      are listed in the ID-list property)

    * Default is an empty string

    * Inherited

    * Can be changed by the trans:idfixup and trans:suffix attributes


How does the "inherited" feature is supposed to work? Does anybody have
a short example?

Thanks!
