Like I said: its just been upgraded.

Its just laziness. We have an implicit trust in the quality of other 
open source products, or, more to the point, know that SVN_HEAD is where 
bug fixes go. Its just Ant's use of XML is limited to DTD-free, 
schema-free, namespace aware XML. We dont see the main problems that you 
may if you go near the PVSI, and dont use bleeding edge APIs that dont 
work in older JVM versions. We also suspect that people running Ant in 
IDEs or embedded use may not even use Xerces, so try not to hard-code 
dependence on Xerces, either.
