# A message describing parse errors is passed to the block.
# Libxml passes error messages to the handler in parts, one per call.
# A typical error results in six calls to this proc, with arguments:
#
# "Entity: line 1: ",
# "parser ",
# "error : ",
# "Opening and ending tag mismatch: foo line 1 and foz\n",
# "<foo><bar/></foz>\n",
# " ^\n"
#
# Note that the error handler is shared by all threads.
