Some answers...

String substitution is still there.  Use this: ${...}

The expression language is OGNL - OGNL is included basically as is in
iBATIS3.  iBATIS will make all bean properties available in the OGNL
context, and also the parameter object itself (as "_parameter").  So
you can do <if test=3D"foo !=3D null">  or <if test=3D"_parameter.foo" !=3D
null">.
