JavaScript: Opening PDFs in a New Window with JavaScript

Opening documents such as PDFs in a new window should be automated using JavaScript for the following reasons. Users will often close the web browser when a PDF is opened, mistakenly believing the document has been opened in Adobe Reader, the attribute historically used to open a new window, target, has been removed from the HTML 4.01 Strict specification (it's now deprecated), opening a new window is a behaviour and should be moved to the behavioural layer.
