I tried adding switching the taskdef to:
<taskdef name="attribute-compiler"
classname="org.apache.commons.attributes.compiler.AttributeCompiler"
classpath="${project.compileClasspathElements}" />
I think this change puts the necessary class on the classpath for the
taskdef, but I still get this error which leads me to believe that it
didn't work.
