This question was posted in response to the following article: http://helpx.adobe.com/indesign/using/create-new-documents.html
Just one comment. The site states that once a document has been created, it is not possible to change the intent of the file. While this was true for InDesign CS5.x versions, this is false for InDesign CS6 where in fact you CAN change the intent after having created the file.
Bart Van de Wiele, thanks for your comment. The text has been updated accordingly.
