Scripts may now return a key–value table, or such a table in addition to a string. The table will be automatically formatted for normal output and will appear as a hierarchy of elements in XML output. Some history and discussion of this development can be found at https://secwiki.org/w/Nmap/Structured_Script_Output. This is a merge of r29484:29569 from /nmap-exp/david/xml-output.
