Conversion of 'Pandoc' documents to Adobe InCopy ICML, a stand-alone XML format
which is a subset of the zipped IDML format for which the documentation is
available here: http://wwwimages.adobe.com/www.adobe.com/content/dam/Adobe/en/devnet/indesign/sdk/cs6/idml/idml-specification.pdf
InCopy is the companion word-processor to Adobe InDesign and ICML documents can be integrated
into InDesign with File -> Place.
