A node is either a CNAME node or an "other data" node. A CNAME node contains only CNAME, KEY, NSEC, and NSEC3 rdatasets along with their covering RRSIG rdatasets. An "other data" node contains any rdataset other than a CNAME or RRSIG(CNAME) rdataset. When changes are made to a node, the CNAME or "other data" state is always consistent with the update, i.e. the most recent change wins. For example, if you have a node which contains a CNAME rdataset, and then add an MX rdataset to it, then the CNAME rdataset will be deleted. Likewise if you have a node containing an MX rdataset and add a CNAME rdataset, the MX rdataset will be deleted. rdatasetsc.VnR#rr5selfs&r __init__ Node.__init__Ys rcj<V^8dQhRS[PPRS[S[S[3,RS[/#)rnamekwr)rr=Namerstrr)rrs"r rNode.__annotate__]s2!!CHHMM!c3h!C!rc \P!4pVPFHp\V4^8gKVP VP !V3/VB4VP R4KJ VP 4RR#)zConvert a node to text format.
