   I just went through the tools/xsltproc.jam and as it reads - it will 
error out if it gets called with an invalid path parameter. Which I do 
not really see anything wrong with.

   So the question is - why are you initializing this toolset in the 
first place?

   If you know where the tool's executable is located - simply pass the 
correct path here. And if you do not have the executable - do not call 
the 'using xsltproc' rule in the first place.

   If you have some sort of customized auto-detection code detecting 
whether you have the xsltproc executable available - simply update it to 
not call 'using xsltproc' if it can not find the executable.

   If your user-config.jam file is stored as a part of your project 
sources then that is something to change. My suggestion is to make it 
part of the documented development environment setup procedure to have 
the developer configure where the needed xsltproc.exe is located in his 
local site-config.jam, user-config.jam or project-config.jam.

   Or, if you are really going for the 'ease of use' - move this code to 
project-config.jam and implement some auto-detection to initialize the 
xsltproc toolset only if it can locate the executable and it has not 
already been initialized by the user's local 
site-config.jam/user-config.jam configuration.

   Hope this helps.

   Best regards,
