Running existing Ant 1.x build files with Ant 2 could be implemented by 
a) recognizing the document is not using the Ant 2 namespace, b) piping 
the content through an XSLT processor.  No need to add a lot of code to 
support backward compatibility.  Hopefully, the syntax will be close 
enough that the transform would be fairly simple.  It would also give 
people a tool to convert an Ant 1.x build file to Ant 2 build file.

<!--  Ant 1   -->

<!--  Ant 2   -->
<project xmlns="">

Any subsequent build.xml breaking change should cause the namespace to 
be changed.

The next minor release after Ant 1.9 should be Ant 1.10 (but it 
hopefully won't get to that).
