This seems (to me) the obvious outcome (although I had to ask).
Can anybody help me with why XERCES depends upon CRIMSON?

Is this an historical dependency? [Would that I had the resources to answer my own questions, but then, I'd still rather get human insights to enhance empirical.]
Because I am evil? ;-)
Ant requires an XML parser. Xerces 2 contained common code (or at least package names) with Xerces 1. The Xerces team routinely used Xerces 1 in their build environment in order to build Xerces 2.
Every once in a while, and completely unbeknownst to the Xerces development team, Xerces 2 would become broken or incomplete, but they would not know it because some aspect of Xerces 1 would "bleed through" the build environment.
Compiling with a non-Xerces compiler allowed such problems to be identified.
