<!-- DPBuddy unzips the file and transforms the files specified in "includes".
It will throw an error if the file is not a well-formed XML.
'transformFiles' supports all attributes and elements of Ant fileset.
You omit "transformFiles" and specify "transform" directly within the task
if the only file being transformed is 'export.xml'

You can reference any Ant property using Groovy variable in the script, e.g., 'env'.
'currentValue' is the variable containing the value of the matched text node or attribute.

<!-- 'dpExclude'/'dpInclude' don't use xpath. Instead, you can simply provide regexps
matching names of DataPower classes and objects. -->
