using xalan line number function with xinclude

Hi all,	

I am building a testing framework for my company using Xalan-based XSL 
with Java backend.

In one of my XSL sheets I am using the nodeinfo:line-number() function 
supplied by Xalan to track line numbers of elements in the input 
document to elements in a generated report document.

Everything worked fine until the input document got too large to be 
easily manageable. Then, I decided to extract sections of it into 
subdocuments and reference those by xinclude elements. Now the 
nodeinfo:line-number() function returns the line number of xinclude 
element instead of the line number in the referenced document. Obviously 
not what I looked for...

Please help, Adrian.
