[elbe-devel] [PATCH] Catch exception in mako template for xsdtoasciidoc

[dion at linutronix.de]

From: Olivier Dion <dion at linutronix.de>

Note: -  max = None 
      +  max = None

      is just removing a whitespace.

If a node doesn't have documentation, an exception is thrown.  This
fix catch the exception and return a "FIX - I have no documentation"
documentation text.
