dispite our less liking of XML, I've made small draft XML config that  
I would like us to consider.

	http://www.opendnssec.se/browser/docs/xml/opendnssec.xml
	http://www.opendnssec.se/browser/docs/xml/opendnssec.rnc

this would allow us to parse all text input as XML. if we want to do  
YAML it would look like this if I understand YAML correctly:

# OpenDNSSEC.yaml
#
HSM:
  sca6000: { Module: /usr/lib/libpkcs11.so, PIN: test:1234 }
  softHSM: { Module: /usr/local/lib/libsofthsm.so, PIN: test:5678 }
#
Enforcer:
  Interval: 3600
  KeygenInterval: 3
  BackupDelay: 3

At first sight, it seems like the YAML is much more compact (and thus  
better), but there are of course other issues lurking. I'd prefer XML  
since it would be only one parser to link to (and we already depend on  
XML for other stuff) and that we'd keep all our config-files in one  
single format, but I really don't care that much if becomes and issue.  
However, I do care that the parsing is done correctly, i.e. if we do  
YAML we parse with a real YAML library (so we can do fancy data  
structures like mappings of mappings) or we do XML (with XPath or the  
like).
