[xsl] loggin SAXON errors

[Bartolomeo Nicolotti <bnicolotti@xxxxxxxxx>]

To whom it may concern,

we use SAXON 2.0 XSLT engine from Java. Is there a way to redirect this
kind of errors:

Error on line 367 of Albatravel_OTA_HotelAvailRS2OTA_HotelAvailRS.xslt:
  XPTY0004: A sequence of more than one item is not allowed as the
second operand of 'to' (1, 1)

from Standard in to a String so that we can put then in a log?

Many thanks

Best regards
