AFAIK 4xslt is written with Python.

In Python, there is a recursion limit which can be changed via two
functions of the sys module:

setrecursionlimit(limit) 
Set the maximum depth of the Python interpreter stack to limit.
This limit prevents infinite recursion from causing an overflow of the C
stack and crashing Python. 
The highest possible limit is platform-dependent. A user may need to set
the limit higher when she has a program that requires deep recursion and
a platform that supports a higher limit. This should be done with care,
because a too-high limit can lead to a crash. 

getrecursionlimit() 
Return the current value of the recursion limit, the maximum depth of the
Python interpreter stack. This limit prevents infinite recursion from
causing an overflow of the C stack and crashing Python. It can be set by
setrecursionlimit(). 

Inserting

        

import
sys

        

sys.setrecursionlimit
(sys.getrecursionlimit()*2) 

At begin of main script can help.

You can contact 4xslt authors too
(http://4suite.org/),
they may add a command line option to change this recursion limit when
calling the tool.
