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/Ulgrr0selfs r __init__ Node.__init__Ys rnamekwrc [R"5nURHGn[U5S:dMUR UR "U40UD65 UR S5 MI UR 5SS$)zConvert a node to text format.

A node which contains a CNAME or RRSIG(CNAME) is a ``NodeKind.CNAME`` node. A node which contains only "neutral" types, i.e. types allowed to co-exist with a CNAME, is a ``NodeKind.NEUTRAL`` node. The neutral types are NSEC, NSEC3, KEY, and their associated RRSIGS. An empty node is also considered neutral. A node which contains some rdataset which is not a CNAME, RRSIG(CNAME), or a neutral type is a a ``NodeKind.REGULAR`` node.
