This module can be used to convert between two of the LMAP (Lightweight
MTA Authentication Protocol) formats currently being proposed:
CID = Microsoft's Caller-ID
SPF = Sender Policy Framework
It will convert an XML-fragment as proposed by CID to a record that can
be added to DNS as proposed by SPF.
This seems to be needed by SpamAssassin/Mail::SPF::Query for dealing
with Hotmail messages, somewhere along the line.
