RefleX can work like this ; for example, you can pack in a zip file 
several resources :
-a master XML document
-some fragments to XInclude
-a DTD
-an XSLT stylesheet
then you can refer any resource in the zip file for 
parsing/validating/xincluding/transforming ; relative paths work too

additionally, the logic itself can be embedded in the same file :

it's not XProc, but you'll find in RefleX very valuable features :
-several useful tag libraries,
-a servlet with its web module library,
-XUnit for testing purpose,
-the ability to browse your file systems with XPath,
-means to design macro tags,
etc
