startParameterEntity() [1] and endParameterEntity() [2] notify you of the 
start and end of a parameter entity. You could just ignore the events in 
between them and write the entity reference instead of its replacement 
text.

SAX requires that parameter entities be reported [3] with '%' prepended to 
their names. XNI adopted this naming convention since that's what SAX 
expects.
