Just one node.

One drawback in the design of s-c-cluster, is its inability to handle 
anything but  its own very rigerous schema. This was done to keep the UI 
from choking on an unknown XML tag. When the conf file is loaded, it is 
checked with xmllint --relaxng, and even if it finds problems and you 
select to continue anyway, it will not persist tag sets it does not know 
about in the output file when changes are made and propagated to the 
cluster.

I have been considering adding the ability for users to add their own 
tag sets and attributes, and have the UI persist them in the model and 
write them back out, but not provide a way to edit them in the UI. This 
would address when support of a new feature lags in the UI (like quorum 
disk) as well as user defined specialty tags.
