[tex-eplain] app.launchURL ()

Does anyone have experience of integrating the PDF function 
"app.launchURL ()" into E-plain ?  At the moment, E-plain emits code 
along the lines of :

  * /Type/Action/S/URI/URI(<url>)

for hyperlinks when using XeTeX (perhaps in other scenarios as well) but 
I need it to emit the correct PDF sequence to invoke "app.launchURL 
(<url>, true)".   If this can be accomplished, a hyperlink from a PDF 
viewed within a web browser would then open in a new window, whereas at 
the moment the link opens in the same window and the original document 
is flushed from the cache.  In the case of (e.g.,) a 50Mb PDF, this can 
then take a very considerable time to re-download and re-display, a 
problem that would disappear if links could be forced to open in a new 
browser window.
