Looks good but you missed a tiny little thing. You need to enclose the xml 
attributes with ' or ". Means in line 12:
<eth name="eth0" mac="00:15:60:56:75:FD" master=bond0 slave=yes/>
=>
<eth name="eth0" mac="00:15:60:56:75:FD" master="bond0" slave="yes"/>
dito for line 13.

When I use your cluster.conf I can see it as follows:
[marc@generix3 ~]$ com-queryclusterconf -f /tmp/cluster.conf nodeids
Traceback (most recent call last):
  File "/usr/bin/com-queryclusterconf", line 97, in ?
    doc = reader.fromStream(file)

line 372, in fromStream

  File "/usr/lib64/python2.4/site-packages/_xmlplus/sax/expatreader.py", line

line 340, in fatalError
    raise exception
xml.sax._exceptions.SAXParseException: <fdopen>:12:62: not well-formed 
(invalid token)
when I change line12/13 like said it looks ok:
[marc@generix3 ~]$ com-queryclusterconf -f /tmp/cluster.conf nodeids
2 1

Hope that helps keep going ;-) .
Regards Marc.
