Thanks a lot Peter and Pasi for your kindly hints.

I have tested some configs for debian wheezy and figured the following 
working one out (s. below).
Best regards, Mark

# To bridge network traffic, like this:
#
# dom0: ----------------- bridge -> real eth0 -> the network
#                            |
# domU: fake eth0 -> vifN.0 -+
#
# use
#
# (network-script network-bridge)
#
# Your default ethernet device is used as the outgoing interface, by 
default.
# To use a different one (e.g. eth1) use
#
# (network-script 'network-bridge netdev=eth1')
#
# The bridge is named xenbr0, by default.  To rename the bridge, use
#
# (network-script 'network-bridge bridge=<name>')
#
# It is possible to use the network-bridge script in more complicated
# scenarios, such as having two outgoing interfaces, with two bridges, and
# two fake interfaces per guest domain.  To do things like this, write
# yourself a wrapper script, and call network-bridge from it, as 
appropriate.
