From fa2c36bbe2e26b29b523fea11c90c56657417d30 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Removed Unknown.java; for mappings in which it is desired to
 process invalid nodes, such as "svg:retc" or "svg:rekt" for svg:rect, the
 DEFAULT mapping option is already provided within an ElementMapping. 
 Removing Unknown gives the ElementMapping implementor the option of halting
 FOP processing and returning an error for such cases instead.
